In the formula for electric potential difference, what does W represent?

In the formula for electric potential difference, the symbol W represents the work done on or by an electric charge as it moves through an electric field. Potential difference is defined as the amount of work required to move a unit charge from one point to another within the field. This relationship can be mathematically expressed as:

[ V = \frac{W}{Q} ]

where ( V ) is the electric potential difference, ( W ) is the work done, and ( Q ) is the charge being moved.

In this context, work is crucial because it quantifies the energy transferred when charges move through an electric potential. This transfer of energy is fundamental to the behavior of electric circuits and the operation of various electrical devices. Understanding that work, in this case, can be seen as energy transferred due to electric forces helps clarify how electric potential difference influences the movement of charges.

The other options involve different concepts: electric field strength is a measure of the force per unit charge and does not directly refer to the energy transferred; potential energy refers to the stored energy due to an object's position in a field; and force applied relates to the push or pull on an object but does not encapsulate the work done when considering charge movement in electric
