Question

If 20 Coulombs of charge passes a point in a circuit in 1 second, what is the value of the current flowing?

The correct answer is

20 Ampere

1 A = 1 C/s Therefore, our calculated value of 20 C/s is equal to 20 Amperes. I = 20 A Comparing with Options The calculated current is 20 Ampere.
