What is the relationship expressed in the voltage formula?

The voltage formula, represented as ( V = \frac{W}{Q} ), where ( V ) stands for voltage, ( W ) for work done, and ( Q ) for charge, shows that voltage is directly proportional to the amount of work done per unit of charge. This means that if you perform more work on a certain amount of charge, the voltage increases. Therefore, understanding this formula highlights how voltage is fundamentally related to the work required to move charged particles in an electric field, making option C the correct choice. This relationship is central to concepts in electricity, as it helps explain how energy is transferred and utilized in electrical circuits.
