Electric current flows only if the circuit is closed.
☆ An electric circuit is said to be a "closed circuit" if it contains a complete path between the positive and negative terminals of its power source (battery).
- When the switch of the electric circuit is turned off or there are some loose connections within the circuit, then it is said to be as an open circuit, since the electric current isn't flowing through the circuit.
- When the switch of the electric circuit is turned on or the connections within the circuit are strong or tight, then it is said to be as a closed circuit, since the electric current is flowing through the circuit.
