Which term is used to describe the electrical potential difference in a circuit?

• A. EMF
• B. Capacitance
• C. Voltage
• D. Inductance

Answer: (C)

Voltage is the electrical potential difference between two points in a circuit. It represents how much energy per unit charge would be converted as charges move from one point to the other, and it’s what pushes current through conductors and components. Measured in volts, voltage is the practical term used for the potential difference you observe across circuit points. EMF describes the energy per unit charge provided by a source itself (like a battery) and can differ from the actual voltage across a source’s terminals in real circuits due to internal resistance. Capacitance and inductance are properties of components—capacitance relates to stored charge per volt, and inductance relates to the opposition to changes in current. So, the term that describes the electrical potential difference in a circuit is voltage.
