A current of 15 amps flows for 8.5 seconds, then the charge is ?
123 J
1.829 J
0.54667 J
None of the other answers are correct

127.5 C

Explanation:

Electric Current is the time rate of flow of electric charges. Mathematically, it is given as:

I = Q / t

Where I = current, Q = charge, t = time

We are looking for charge, Q, so we make Q subject of the formula:

Q = I * t

Hence, for a current of 15 Amps that flowed in 8.5 seconds, the charge is:

Q = 15 * 8.5

Q = 127.5 C

The unit of charge is Coulomb (C)
