Electrical current is the flow of electrical charges. It transmits energy called electricity.
Electrical current flows differently, depending on the type of material through it flows.
- Conductors : electrical current flows easily through conductors. Most metals are conductors.
- Insulators: electrical current does not flow easily through insulators, such as air, glass, plastic, wood and rubber.
