Question

An electric appliance draws a current of 0.4 ampere when voltage is200 volt calculate the amount of charge flowing in 1 hour

Answer 1

Q = it
= 0.4 A × 60 × 60 seconds
= 1440 Coulomb

Amount of charge flowing in 1 hour is 1440 Coulomb

Answer 2

Answer:

The amount of charge flowing in 1 hour is 1440 coulomb.

Explanation:

here, current, I = 0.4 A

        voltage, v = 200 V

since, the current flowing in the circuit is the rate of flow of charge through the cross section of the conductor with respect to time.

so, I= amount of charge (q) / time

here, time, t = 1 hour = 60*60 sec

now, q = I*t

         q = 0.4*60*60

         q = 1440 coulomb.
