Question

A current of 0.75 A is drawn by a filament of an electric bulb for 20 minutes . Find out the amount of electric charge that flows through the circuit

Answer 1

Answer:

900C

Explanation:

q=it

q=0.75x20x60

900C

Answer 2

Answer:

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= Q/t.Q=i×t=0.25×20×60=300C.
