Appliance: a machine or piece of equipment that performs as task.

Battery: a device that contains one or more cells and produces chemical energy which is converted into electrical power

Bulb: piece of glass that changes electricity into light with a piece of metal inside & electrical current.

Buzzer: a device that hums when an electrical current is passing through it (is not required).

Cell: single unit that produces chemical energy which is converted to power (batteries are made of these cells).

Component: parts of a circuit (i.e. cell, motor, switch etc).

Conductivity: a stage of which a conductor allows for electrical current to flow through it.

Connection: when electrical components are linked together.

Resistor: a component that limits the amount of electric current that can flow through a circuit.

Terminal: part of a cell that makes a connection with a circuit (they’re negative & positive).

Fuse: device that can break an electric circuit if needed.

Voltage: the force of an electrical current is measured in volts.

Motor: a machine that is powered by electricity and supplies power to a device.

Power: electric power is the rate of electric energy passed through a circuit.

Resistance: the degree to which the flow of electrical current through a circuit is slowed or stopped.
