Question

What do you mean by an electric circuit? Draw the circuit diagram for a circuit having three cells, one bulb and a switch.

Answer 1

An electric circuit is a closed path through which the current flows. An electric circuit comprises a switch, a bulb, a cell, etc.When the switch is closed, the circuit is complete and current starts flowing through it. On the other hand, when the switch is open, the circuit is open or incomplete; hence, current stops flowing through it.
