Question

A current of 0.5A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through the circuit.

Answer 1

we know that I=Q/t
∵1min=60sec
then, 10min=?
therefore 10min=600sec

so 0.5=Q/600
now 0.5*600=Q
Q=300C
therefore charge is 300C

Answer 2

We are given, I = 0.5 A; the = 10 min = 600s.

We have

Q = It

= 0.5 A * 600s

= 300c
