Question

An electric bulb draws a current of 0.2A when voltage is 20 V. Calculate the amount of electric charge flowing through it in 1 hour

Answer 1

1 ampere = 1 coulomb per second 0.2 amperes = 0.2 coulombs per second = 720 coulombs per hour

Answer 2

ANSWER...

• It is given that an electric bulb draws a current of 0.2 ampere when the voltage is 220 volts. where, Q = Charge and t = time taken. Therefore, 720 C is the amount of electric charge flowing through it in one hour.
