Which of the following is the correct unit of measure for the voltage in an electrical circuit?

The correct unit of measure for voltage in an electrical circuit is the volt. Voltage represents the electric potential difference between two points in a circuit, essentially indicating the energy per unit charge available to drive an electric current. In the International System of Units (SI), the volt is the standard unit for measuring this potential difference.

To provide additional context, ohms are the unit of measurement for electrical resistance in a circuit, while watts measure power, which is the rate at which energy is transferred or converted. Henry is the unit of inductance, which relates to how much a coil or circuit resists changes in current. Understanding these distinctions is crucial for grasping the key concepts in electrical systems and engineering.
