What is the term for the potential difference between two points in a circuit?

The term for the potential difference between two points in a circuit is voltage. Voltage is a measure of the electric potential energy per unit charge and indicates how much work can be done by electric charges when they move through a circuit. It is often represented by the symbol V and is measured in volts. The concept of voltage is fundamental in understanding how electrical circuits function, as it drives the flow of current through the circuit.

Current refers to the flow of electric charge, while resistance is a measure of how much a material opposes the flow of that charge. Both of these concepts are directly related to voltage through Ohm's Law, which states that voltage equals current times resistance. Therefore, understanding voltage is crucial for analyzing and designing electrical systems.
