Question

a current of 0.5 A is drawn by a filament of an electric bulb for 10 min. find the amount of electric charge that flows through the current?

Answer 1

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

current, I = 0.5 A

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

let the total charge flown = Q

Q=600×0.5=300C
