Resource summary
Electricity KS3 Y7
Electric current
The flow of electrical charge
Measured in amps or amperes
Always placed in series
In a series circuit, the current is the same everywhere
Series means all components are connected
Parallel means all components aren't connected
Resistance
The more resistance in a circuit
The lower the components will work
The less resistance in a series
The better the component will work
The way the cell faces matters
The cell will not work if it is reversed biased
Diodes
Led's
Ldr's
The ldr's need resistance or their will be too less resistance
If the current is flowing against an led it won't work
Ldr stands for Light dependent resistor
Led stands for light emitting diode
An ldr has high resistance in the light
In the dark, an Ldr's resistance is low
A SPDT has two switches which control two circuits
