1 resistor (n.) ตัวต้านทานการ ไหลของกระแส ไฟฟ้า A resistor restricts the flow of current, for example to limit the current passing through an LED.
2 variable resistor (n.) ตัวต้านทานปรับ ค่าได้
3 capacitor (n.) ตัวเก็บประจุ
4 polarized capacitor (n.)
5 variable capacitor (n.) ตัวเก็บประจุแบบ มีขั้ว
ตัวเก็บประจุปรับ ค่าได้ A rheostat (a type of variable resistor) is usually used to control current like adjusting lamp brightness.
A capacitor stores electric charge. A capacitor is used with a resistor in a timing circuit. It can also be used as a filter, to block DC signals but pass AC signals.
Electrolytic capacitor is one type of polarized capacitors; one terminal must always have positive potential with respect to the other.
A variable capacitor is used in a radio tuner.
6 diode (n.) ไดโอด A diode is a device which only allows current to flow in one direction.
7 LED light emitting diode (n.) ไดโอดเปล่งแสง A transducer which converts electrical energy to light is called a light emitting Diode.

9 photodiode (n.) ไดโอดแปลค่าตาม ความเข็มของแสง A light-sensitive diode, called a photodiode, converts light in to current or voltage.
10 transistor (n.) ทรานซิสเตอร์
11 phototransistor (n.) ทรานซิสเตอร์แปล ค่าตามความเข็ม ของแสง A transistor amplifies current. It can be used with other components to make an amplifier or switching circuit.
A light-sensitive transistor, called a phototransistor, is used to amplify current.
12 microphone (n.) ไมโครโฟน A microphone is a transducer which converts sound to electrical energy.
13 earphone (n.) หูฟัง An earphone is a transducer which converts electrical energy to sound.
14 loudspeaker (n.) ล�าโพง A loudspeaker is a transducer which converts electrical energy to sound.
15 amplifier (n.) เครื่องขยายเสียง An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds.
16 antenna (n.) เสาอากาศ A device which is designed to receive or transmit radio signals is known as an antenna.
