Question

Find the amount of electric charge flowing through the circuit if an electric current of 5 A is drawn by an electric appliance for 5 minutes.

Answer 1

Given,

Current, I = 5 A
Time, t = 5 minutes = $60\times 5$ = 300 sec
We know that,

Current, ​I = $\frac{Q}{t}$
Therefore, 5 = $\frac{Q}{300}$
Q = $300\times 5$ C
Q = 1500 C.
