Question

A current of 0.25 ampere is flowing through a filament of an electric bulb for 20 min. Find the amount of electric charge that flows through the circuit.

Answer 1

Explanation:

A current (i) is flowing through the filament of an electric bulb for time t=20minIf a net charge Q, flows across any cross-section of a conductor in time t, then the current i, through the cross-section is, i=tQQ=i×t=0.25×20×60=300C
