Answer: Correct option is (a) Work done / (Current × Time)

Voltage is defined as the electromotive force that indicates the energy per unit charge. In short, the difference in the electric potential between two points is referred to as voltage.

Unit of voltage (SI) = Volts (V)

The electric potential is work done per unit charge

Electric potential = Work done/Charge

Charge = Current (I) × Time (t).

So,

Electric potential = Work done / (Current × Time)

Voltage is also known as the electric potential

Voltage = Work done / (Current × Time).
