Question

A current of 1 ampere, is drawn for 20 minutes find the amount of charge flows through it?

Answer 1

do this way

Solution:

GIVEN:

Current (I)= 0.25 A

Time(t)= 20 min

t= 20 × 60= 1200 seconds

[1 minute= 60 seconds]

We know that,

I = Q/t

0.25 = Q/1200

Q= 0.25 × 1200

Q= 300 C

Hence, the amount of electric charge that flows through the circuit is 300 coulombs.
