What does a volt measure?

• A. Current
• B. Power
• C. Voltage
• D. Resistance

Answer: (C)

A volt is a unit of measurement that quantifies voltage, which is the electric potential difference between two points in an electric circuit. Voltage can be thought of as the force that pushes electric current through a conductor. It is an essential concept in understanding electrical circuits, as it helps determine how much electric potential is available to drive the current.

In contrast, other terms encompass different concepts within electrical systems: current is measured in amperes, power is measured in watts (which is a function of both voltage and current), and resistance is measured in ohms. Understanding voltage is crucial for anyone working with electrical systems, as it affects the operation and safety of circuits.
