What is the formula for electric potential difference?

The formula for electric potential difference is indeed represented as the work done per unit charge. This relationship is captured in the formula ( \Delta V = \frac{W}{q} ), where ( \Delta V ) represents the electric potential difference (also known as voltage), ( W ) is the work done on the charge, and ( q ) is the amount of charge. This formula highlights that the potential difference between two points in an electric circuit indicates how much energy is being transferred to the charge per unit charge as it moves through the electric field.

In the context of electric circuits and fields, understanding this formula is crucial because it helps quantify the energy available to drive a charge through a circuit. The higher the potential difference, the greater the energy that charges can gain as they move through the circuit.

The other formulas, though related to electrical phenomena, address different concepts. For example, the equation ( \Delta V = qE ) relates electric potential difference to the electric field strength but is not a standalone definition. The formula ( \Delta V = RC ) concerns the time constant in RC circuits, and ( \Delta V = \frac{F}{S} ) (where ( F ) is force and
