In an electrolytic cell, 5 A of current passes for about 3.5 minutes. The amount of electric charge equals:

A 17.5 coulombs
B 85.7 coulombs
C 1050 coulombs
D 96500 x 5 x 3.5 coulombs


Ans. C Ampere is defined as the total amount of charge that flows per second.

The charge in coulombs = 5 A x 3.5 min. x 60 s/ 1 min. = 1050 coulombs.
