What does a volt measure in electrical terms?

A volt measures the pressure or force of an electric current, often referred to as electric potential difference. This concept is fundamental in understanding how electricity flows through a circuit. When a voltage is applied across a circuit, it creates a potential difference that drives electric charges to move, resulting in current flow.

In the context of the other options, resistance is measured in ohms, which quantifies how much a material opposes the flow of electricity. The amount of energy consumed is typically measured in watts, which represents power, calculated by multiplying voltage by current. Frequency, on the other hand, is measured in hertz and pertains to how often the current changes direction in alternating current (AC) systems, rather than the force driving the current. Therefore, recognizing that voltage relates to the pressure or force of the current is essential for understanding electrical principles and how circuits operate.
