Mind maps
FT
These are a really useful visual summary of information and you can put them on the wall. They allow you to show links between ideas and concepts. You can start by adding the topic to the centre of the diagram and then add the sub-topics around that and a summary of the information.
Current out of positive – COUP
Measured in volts, V
The flow of electrons around a circuit Measured in amps, A
V
The difference in electric potential between two points in a circuit
Ohm’s law – V = IR
Current
Potential difference
A
A
Also known as voltage
Can be AC or DC Watt’s law – P = IV
R

ELECTRONIC CIRCUIT PARAMETERS
Measured in ohms, Ω Resistance The opposition to the flow of current around a circuit
Measured in watts, W
D
The rate at which electrical energy is transferred by a circuit
Measured in farads, F
Capacitance
The amount of charge that a component or circuit can store
Frequency
Measured in hertz, Hz
The number of waves that pass a fixed point over a set time period
