Question

A current of 0.5A is drawn by a filament of an electric bulb for 20 minutes.Find the amount of electric charge that flows through the circuit

Answer 1

electric current = 0.5A. (I)
Time = 20×60=120sec (t)
electric charge = q
so

I = q/t
0.5 = q/120
q = 0.5×120
q = 60 C

Answer 2

Answer: The amount of electric charge will be 600 C.

Explanation:

Given that,

Current I = 0.5 A

Time t = 20 minutes

We know that,

The amount of electric charge is the product of the current and time.

$q = it$

$q =0.5\times20\times60$

$q = 600\ C$

Hence, The amount of electric charge will be 600 C.
