Electric current
- The flow of free electrons (or charge) in a definite direction is called electric current.
- The flow of electric current you can show in below diagram....
- The copper strip has large number of free electrons. When electric pressure voltage is applied, the free electron being negatively charged start moving towards the positive terminal around the circuit.
- This directed slow of electrons is called electric current.
- Conventionally, the direction of the electric current is taken along the direction of motion of positive charges. When current is caused by electrons (e.g. in metals), the direction of current is opposite to the direction of electrons flow.
