What term is used to describe electrical pressure within a circuit?

The term used to describe electrical pressure within a circuit is voltage. Voltage is a measure of the potential energy that drives electric charges through a conductor. It can be thought of as the force that pushes electrons through a circuit, much like water pressure pushes water through pipes. This electrical pressure is crucial for the flow of current, as it creates the difference in electric potential needed for current to move.

Current refers to the flow of electric charge in a circuit, while resistance measures how much a component opposes this flow. Power, on the other hand, indicates the rate at which electrical energy is consumed or produced. Understanding voltage is fundamental in grasping how electrical circuits function, as it directly impacts both current flow and the overall operation of various electrical devices.
