Kids,switch!”can
To ensure appliances can receive the electrical energy provided by an energy source like a battery, we must use a wire to form a closed loop by connecting the battery to the appliance. A conducting loop that consists of metal wires and electric components is called a circuit. A simple circuit consists of power, a switch, wire and appliances. A simple circuit with a lamp can make it light up. Are there switches for the lamps in the street light? How will you design the switches?
“The switches in the street lamps are controlled by the electricity company. They observe the hours of sunrise and sunset as reference for the switches but of course there are some special street lights that use automatic light sensor systems to observe natural brightness and automatically switch themselves off and on. Light can be used to trigger simple circuits, like a you make a simple circuit to power a street light?

Gigi saw a breaker panel on the wall of her home and out of curiosity she asked grandma about the functions of the breaker panel.
Electricity is a necessary source of energy in all homes, and breaker panels are a tool that helps families control electricity. Therefore, maintaining a functioning breaker panel is very important. Breaker panels should be placed in open areas and not blocked, so that when an electrical accident happens, the power can be immediately restored. Kids, do you know where the breaker panel is in your home?

It’s cold in winter, and many of us like to turn on an electric heater to warm ourselvesup. However, electric heaters consume a lot of power, which may result in wires melting or becoming damaged with careless use. Therefore, we must buy electrical appliances that are certified as safe. We must correctly assemble them and observe their safety notices. For instance, we should not use extension cords or leave them on for more than four hours at a time.

In a distribution box, the first switch is the master which controls power into the main breaker panel. The lamps will not power up if it is off. The rest of the switches control the power supply to specific circuits in the house so some areas can be turned off without interfering with others. Distribution boxes contain multiple circuits, both in series and parallel.
After attending school, Gogo found he had less time to play with his Father. After supper they often took a walk together. One day when they walked under the moon, Gogo suddenly found the road was darker, and that a lamp was not working. He stopped and looked around to discover that all the lamps were working except one, just in front of him. So he asked why the damaged lamp didn’t affect the others. His Father praised his careful observation and told him that lamps are connected in a parallel circuit, so the rest of the lamps can still work even if one of them is broken. Moreover, several lamps are divided into zones via a series switch. A circuit including both series and parallel circuits forms a multiple circuit.

Car Recently, a light went out in Gigi’s home. Gigi discovered that all the lights at home were different levels of brightness. Some were very bright, while others were quite dim. Gigi wanted to find out why, so she asked her Daddy. Her Father told her, “The lights at home are made up of different types of circuit, some use series while others use parallel, take a look.”
A long electric torch requires two or three batteries which all face the same direction, thus the batteries are connected in series via their positive and negative poles. The corresponding circuit is called a series circuit and the voltage provided is equal to the sum of the voltage across the two ends of each component.What activities or mechanisms in everyday life work the same way as a series connection?
Dad pointed at the ceiling light and said: “The reason this row of lights is dim is because they use a series circuit. When these light bulbs are linked by a series circuit to one power source, the electricity is dispersed among them causing them to fight for current and voltage; therefore, when lightbulbs are linked by a series circuit, they aren’t as bright. However, this doesn’t mean that series circuits are bad, they can be used to conserve energy because additional light bulbs do not increase electricity consumption.”

Parallel Applications Scientific Application Today Gigi was enjoying some family shopping time at the department store with her mom.
Her Mom then said: “A parallel circuit refers to when both ends of the power source are connected to each appliance, therefore the voltage and current received by each appliance is the same. Also, because each appliance runs on an individual power source, so even if one fan breaks, the other fans will continue to function. Naturally, parallel circuits have certain disadvantages like each additional appliance increasing the total energy consumption; also, the additional cables will increase Kids,costs.”think about the pros and cons of parallel circuits using batteries.
31 Brainstorming 8 ElectricParallel Car
Gigi’s Mom, however, told her: “Actually, each shop uses electricity provided by the department store, but because they use a parallel circuit, they won’t affect each other.”
Most of the extension cords in our home are a kind of parallel circuit. Each of them can provide the same voltage to connected appliances allowing them to operate using their usual power level. Parallel connections run between two ends of several components with two nodes. In a parallel circuit, the current provided is equal to the sum of the currents of each connected component. The voltage is also equal to the sum of the voltages of each of the connected components.
While shopping for clothes, she suddenly felt hot and stuffy because the fan in the clothing shop was broken. Gigi saw that the fans in other shops were still functioning, so Gigi thought it was because each shop used a different power source.

Circuit Test Scientific Application
Gigi has a favorite electric toy tank she loves to play with, she is reluctant to share it with other kids.
One day, when Gogo came to her home, she showed it off but she found the gun-turret wouldn’t rotate. The tank wasn’t working! Everything had been fine when she was playing with it the day before! How could it be broken now? Gigi was frightened and had no idea what to do. Gogo said he could check it for problems, so he found a small lamp and some wires from the toy box to make a simple electroscope. He first connected the battery to the lamp to make sure everything was working okay. He confirmed the battery had no problems.
Generally, voltmeters are used for circuit testing to see the three physical quantities of current (amps), voltage (volts) and resistance (ohms), hence they are sometimes called volt-ohm-milliammeters.
Next, he connected the wiring on both sides of the motor to the electroscope and found that the lamp didn’t work. This meant that there was something wrong in the wiring, so the motor didn’t have any power to work! Finally, they found the loose connection.

The batteries we often use today are still mostly based on those invented by physicist Alessandro Volta. He first built batteries following the experiments of the Italian Doctor Galvanic. When Galvanic dissected frogs, he discovered that where his scalpel touched the exposed nerves on the frog’s legs, the leg began to twitch violently. He called this phenomenon bio-electricity. Volta based his research on Galvanic’s experiments using two different types of metals for conductivity. He found that the frog’s legs reacted to electricity instead of producing it. Later, Volta used a saline soaked cloth clamped onto zinc and silver discs stacked in a column to produce a kind of battery effect. A conduction cable was needed to link the topmost silver disc with the bottommost zinc disc, thus producing a circuit. This allowed scientists to produce a stable and continuous flow of electricity to conduct other electrical research investigations, resulting in rapid advancements in the field of electricity.
What are the differences between the various models of batteries currently sold on the market?

Electric current flows are quite similar water flows. People frequently analyze information about water flows using electrical terminology. This is called making an analogy. Analogy compares the similarity between two things to infer new ideas about one of the subjects. If you encounter something new or strange, you can try thinking of an analogy.

Thecould.teacher wrapped the iron nail in the enameled wire and completed the circuit. After the teacher turned on the power, when the nail got near the paper clips they were all attracted to the nail. This proved that electric currents can produce magnetism. Everyone gasped in amazement! Gogo enjoyed these electromagnetic experiments very much and went online to find more information. He discovered that a soft iron rod and a spiral circuit could create a stronger effect, so he gathered the materials in preparation for his own project.

Industrial electromagnets are a common sight at waste iron recycling centers. Electromagnetic cranes run along a track, rather than on wheels. Attached to a giant electromagnet, they move back and forth along the track, lifting things. Once electrified, the electromagnet can lift up waste iron and move it. Once the power is off, the magnetic field disappears and the iron waste is released. This method can eliminate the need for the human packing process.

Theclip. teacher came in and announced the topic of the class would be electromagnetic effects. The teacher then asked: “Students, do you think an electric current can cause an iron nail to magnetize and attract the paper clips?” Everyone thought about it, and some didn’t think it was possible while others thought it

One night while watching TV, Gogo heard a weird motor sound coming from his Dad’s room. Curious, Gogo went to see what was going on. It was his Dad using an electric razor to shave his beard. Gogo thought the electric razor seemed very convenient so he asked his dad how the electric razor functioned. His Dad said: “When you turn on the electric razor, the razor’s circuit is filled with a current. Through the magnetic induction effect causes rotation inside of the razor, converting electricity into kinetic energy.” Upon hearing this, Gogo said, “I get it! Motor’s work on the same principle.” Gogo’s Dad praised him, and encouraged him to think about what other materials could be used in the razor’s coil to make it rotate using electrical induction.
Motors have broad applications in our everyday lives, they can be found in many places. The magnetic effect of currents can be used to create kinetic energy. When using motors, we must pay attention to how the motor is operating to prevent damage or risk burn-out if it is under strain.

After Gogo understood the principle behind motors, a question formed in his mind: “If electric currents can produce kinetic energy, then can kinetic energy produce currents?”
Kids, do you know the difference between motors and generators?
Hand cranked generators are an application of electromagnetic induction. The generator is equipped with a magnet and coil. An inward and outward movementcauses the magnet generate charge in the coil. The changes in the magnetic field produces a current that is stored in a simple battery. The battery can then provide power to devices during a power outage.

So Gogo went to his good friend Gigi and the two of them thought of an experiment. They prepared a metal ring and covered it with coils, then connected the coils to a current Theydetector.started the experiment when Gogo moved a magnet near the coil and the current detector began to rotate. Gogo then removed the magnet from the coil and the current detector rotated again. This proved that changes in the magnetic field could produce temporary currents, causing the current detector to rotate. The two of them excitedly told their physics teacher about the good news. The teacher said: “You two are amazing! This is actually one of the key experiments in electromagnetic induction and the generators we use are based on this principle.”

If we make good use of our ingenuity, we can use many applications from our daily lives to produce electricity. For example, batteries inside multi-functional backpacks could store electricity from solar panels installed on the outside. During sunny days, you could rely on the battery alone, and on cloudy days, the alternating current can be used to charge the battery, making it very convenient for outdoor activities.
What other actions in our daily lives could we use to generate electricity?

Today is the annual Maker’s Fair and Gigi’s mom brought her to the exhibition to see interesting creations. The theme of this year’s Maker’s Fair is “green energy”. At the venue, Gigi saw many power generating ideas. Each piece was unique whether they were powered by water or wind. The thing that attracted Gigi the most was power generating shoes. The exhibit staff told Gigi: “Power generating shoes use two piezoelectric discs in place of in-soles so that the pressure generated when people walk, run, or jump will be converted into kinetic energy within the shoes. The magnets moving inside produces electricity, thus achieving the effect of generating power through walking.”
After hearing this, Gigi thought it was very interesting and wanted to generate power through one of her favorite exercises. Her Mom curiously asked Gigi what that was. Gigi answered, “It’s probably sleeping!” Both Mother and daughter couldn’t help but laugh, creating a happy memory at the exhibition.
