If the current in an electric conductor is 2.4 A, how many coulombs of charge pass any point in a 30-second interval?
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
The amount of charge that passes any point in a 30 sec time is 72C.
