Which statement about voltage is true?

Explanation:
Voltage is the electrical potential difference between two points. This is the precise quantity used in circuits and what a voltmeter reads. It represents the work done per unit charge to move a charge from one point to the other and is the driving force behind current when a path exists. The analogy of electrical pressure is helpful but not the formal definition. Current is the flow of charge, not voltage itself, and Ohm’s law links them through resistance. Saying voltage can be AC or DC describes the waveform it can have, which is true but describes its behavior rather than what voltage is.
