1 Electric Current Electric current is an electric charge in motion. Materials that allow electrons to flow easily through them are called conductors of electricity.Ex. Copper, silver, iron, etc.
2 Electric CurrentMaterials that resist the flow of electrons are nonconductors which are called insulators.Ex. Wood, glass, rubber, plastic, etc.These help prevent electrical shock to someone who touches a wire that is carrying an electric current.
3 Closed/Open CircuitsElectricity must have a complete path from the power source, through the circuit, and back to the source, this is called a closed circuit.
4 Closed/Open CircuitsIf the path of electric current is broken, the circuit is incomplete and is called an open circuit.
