Question

If the current through a floodlamp is 5 A, what charge passed in 10 seconds?

(a) 0.5 C
(b) 2 C
(c) 5 C
(d) 50 C

Answer 1

(d) 50 C

Here, current, I = 5 A
Time, t = 10 s
So, using the relation, I = Q/t:
Q = I x t
Charge, Q = 5 x 10 = 50 C
Thus, a charge of 50 C is passed in 10 s.
Hence, the correct option is (d) 50 C.
