Question

A current of 0.5 A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through the circuit.
(1) 100C(2) 200C(3) 300C(4) 400C

Answer 1

Answer:

current, I = 0.5 A

time, t = 10 minute = 10×60 = 600 seconds

let the total charge flown = Q

I=

$\frac{Q}{t} \\ \\Q=I*t\\ \\Q=0.5*600\ C\\ \\Q =\boxed{300\ C}$

Answer 2

Explanation:

Current flowing=0.5A

Hence, 0.5 C of charge is flowing through the bulb each second (as A=C/s)

hence, in ten minutes,

• 0.5*600=300C
