Reference: AQA
The energy transferred when a force moves its point of application through a displacement in the direction of the force.
Given by W = QΔV when charge Q moves through a potential difference ΔV, whether the field is uniform or non-uniform.
Force × displacement × cos θ, where θ is the angle between the force and the displacement.
Calculated using W = qΔV when a charge moves through a potential difference.
