Question

The filament of an electric bulb which draws a current of 0.2 A is used for 5 hours .calculate the amount of charge flowing through the circuit

Answer 1

Explanation:

First we have to change Time unit in second = 5 × 3600 sec

= 18000 sec

Now we know that

current (I) = charge (Q) / Time(t)

so Q = I × T

= 0.2 × 18000

= 3600 C
