Electric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. The circuit includes an energy source like a battery that produces voltage. Without voltage, electrons move randomly and are undirected and current cannot flow. Voltage creates pressure on the electrons which channelises it to flow in a single direction.
The four effects of electricity are
- Magnetic effect
- Chemical effect
- Heating effect
- Electric shocks.
