Current, Charge Potential Difference - A-Level Physics The potential difference between any two points in a circuit is the measure of work done by an electron to move from one point to another Potential energy is measured in volts (V) and energy is measured in joules (J)
Electric Circuits: Potential Difference – A Level Physics Edexcel . . . Potential difference (V), also known as voltage, is the work done or energy transferred per unit charge It is measured in volts (V), where one volt equates to one joule of energy transferred per one coulomb of charge (1V = 1J C)
OCR A Physics A-level - Physics Maths Tutor It is defined as the energy transferred from electrical energy to other forms, per unit charge, It is measured in volts (V), where a potential difference of 1 volt is defined as 1 joule of energy transferred per coulomb
