A circuit has a current of 3 A. How many coulombs of charge will pass by a point in the circuit in 2 seconds?

- 6C

- 5C

- 3/2 C

- 2/3 C

One of these are the answer..

6C

The quantity of charge, Q, passing through an electric circuit is dependent on the electric current, I, and the time taken, t, for the current to flow. It is given mathematically as follows

Q = I x t          (i)

Where;

I is measured in Amperes(A)

t is measured in seconds (s)

Q is measure in coulombs (C)

From the question,

I = 3A

t = 2s

Substitute these values into equation (i) as follows;

Q = 3 x 2

Q = 6C

Therefore, the number of coulombs of charge that will pass is 6C
