Current x is 2.5 a and runs for 39 seconds. current y is 3.8 a and runs for 24 seconds. which current delivered more charge, and how much more charge did it deliver? a) x delivered 97.5 c more than y. b) x delivered 6.3 c more than y. c) y delivered 91.2 c more than x. d) y delivered 1.3 c more than x.

The relationship between Charge(Q), current (I) and time(t) is given by

First we find charge from X and then from Y

For X:

I= 2.5 A, t= 39 sec

For Y:

I= 3.8 A, t= 24 sec

As from the calculation Current X delivered more charge than Y by

Therefore, X delivered 6.3 C more than Y
