Heater
Converts electrical energy into heat.
.
Potential Divider
Divides voltage within a circuit.
.
Transformer
Changes the voltage from one circuit to another through electromagnetic induction.
.
Switch
Opens or closes an electrical circuit, controlling the flow of current.
.
Magnetising Coil
Creates a magnetic field when current passes through it.
.
Earth or Ground
A reference point in an electrical circuit from which voltages are measured, and a return path for current.
.
Junction of Conductors
Indicates wires that are electrically connected.
.
Lamp
Converts electrical energy into light.
.
Motor
Converts electrical energy into mechanical energy.

Generator
Converts mechanical energy into electrical energy.
.
Ammeter
Measures the current flowing through a circuit.
.
Voltmeter
Measures the electrical potential difference between two points in a circuit.
.
Diode
Allows current to flow in only one direction.
.
Light-Emitting Diode
Emits light when current passes through it in the proper direction.
.
Fuse
Protects circuits by breaking the circuit if current is too high.
.
Relay Coil
An electromagnet that opens or closes contacts in another part of the circuit.
