ANSWER
Answer is C.
The power supply (the cell or battery) gives an amount of energy to each coulomb of charge in an electric circuit.
so, voltage = energy / charge.
This equation can be rearranged to give energy = voltage * charge. E = V * Q.
Since Q = I * t, if we write I * t instead of Q in the above equation we get E = V * I * t.
Energy = voltage * current * time.
We can also use the word work instead of the word energy because,
work done = energy transferred
so, we might see the equation energy = voltage x charge, E = V * Q, written as
work = voltage x charge, W = V * Q.
Therefore, V=W/Q and not WQ. Hence, option C is incorrect.
