Which term describes the electrical potential difference from a source such as a battery?

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

Answer: (B)

Voltage is the electrical potential difference between two points, such as the positive and negative terminals of a battery. This potential difference is what pushes electric charges through a circuit when a path is closed, and it’s measured in volts. In a battery, the terminal voltage represents how much energy per unit charge is available to drive current. Current is the actual flow of charges, resistance is the opposition to that flow, and capacitance is the ability to store charge. So the term describing the potential difference from a source like a battery is voltage.
