Question

When the light bulb is lit, a current is flowing through it. what condition must be met so that a current flows

Answer 1

Closed loop, conductor medium and presence of current in the wire are the conditions must be met so that a current flows.

What are the basic conditions for the flow of electric current?

The loop from where the current passes must be closed. There must be some current in the circuit in order to lit the bulb. The medium through which current flows should be a conductor.

So we can conclude that closed loop, conductor medium and presence of current in the wire are the conditions must be met so that a current flows.
