What is the unit used to measure voltage?

• A. Ohm (Ω)
• B. Watt (W)
• C. Volt (V)
• D. Ampere (A)

Answer: (C)

The unit used to measure voltage is the volt, denoted by the symbol 'V.' Voltage, or electric potential difference, represents the work done to move a unit charge between two points in an electric field. Essentially, it quantifies how much potential energy is available to drive electric currents through resistive components in a circuit. Understanding voltage is crucial in electrical engineering as it directly influences how electrical circuits function; higher voltage can push more current through a circuit. The volt is part of the International System of Units (SI) and is defined as the potential difference that will move one coulomb of charge against one joule of energy. In contrast, the other units mentioned have different purposes. Ohms measure electrical resistance, watts measure power (the rate of energy transfer), and amperes measure electric current. Each of these units plays a vital role in electrical systems but does not directly measure voltage.
