Current-the rate at which electric charges pass through a conductor

Ampere-the unit that represents current

Ohm-the unit that represents resistance

Voltage-the unit that represents potential difference

Ohm’s Law-states that voltage is equal to the current times the resistance in a circuit

Resistance-the opposition to electric current by a material or device

Electric power-the rate of conversion of electrical energy

Schematic diagram-a representation of a circuit that uses lines to represent wires and different symbols to represent the components of the circuit

Electric circuit-a set of components connected so that they provide a path for the movement of charge.

Series circuit-a circuit that provide a single path for the flow of current

Parallel circuit-a circuit that provides multiple paths for the flow of current

Complex circuit-a circuit that consist of series and parallel circuits combined

Fuse-a small metallic strip that melts if the current exceeds a certain value

Circuit breaker-an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit

Ammeter-a device that measures the amount of current across a load

Voltmeter-a device that measures the amount of voltage across a load
