Question

an electric bulb draws a current of 0.2 amp when the voltage is 220 volts calculate the ammount of electric charge moving through in 1 hours

Answer 1

current I = 0.2 A

and time t = 60 * 60 *60 = 216000

as charge q = It = 0.2 * 216000 = 43200

Answer 2

electric charge (I) = 0.2 A

potential difference (V)= 220 V

time (t) = 1 hour
= 3600 seconds

now,
Amount of electric charge flowing (q)= I×t
= 0.2 x 3600 = 720 C.
