Question

If the current in an electric conductor is 2.4 A, how many coulombs of charge pass any point in a 30-second interval?

Answer

Given data:

current I = 2.4 sec

Time t= 30 sec

Charge Q= ?

We know that current = charge / time

I = Q/t

Q = I * t

Q =  30 sec*2.4 A

   =   72C

The amount of charge that passes any point in a 30 sec time is 72C.
