Question

what is circuit?what is a closed circuit​

Answer 1

Answer:

A conductive path where electric current flows through it is known as an electric circuit. A closed circuit is when the current flows through the conductor, that is, the switch is on.

If the switch is off, current stops flowing in the circuit and hence the circuit is open.

Hope this helps!

Answer 2

Answer:

1. An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.
2. A circuit without interruption, providing a continuous path through which a current can flow.
