Question

A conductor carries a current of 0.4A Find the amount of charge that pass through the cross section of the conductor in 1.5 minutes.

Answer 1

WE KNOW THAT , 
                         I = Q/T
                         or Q= IT
                         ======> WE HAVE, I = 0.4 A
                                                           T = 1.5 MIN = 1.5 * 60 = 90 s
                   THEREFORE, Q = 0.4 * 90
                                                = 36 c
