Question

potential difference is measured in which units?
volts
amps
currents
watts

Explanation:

To determine the unit of potential difference, we recall the definitions of each option:

• Volts: The SI unit of potential difference (or voltage) is the volt. It represents the amount of energy per unit charge between two points in an electric circuit.
• Amps: Amperes (amps) are the unit of electric current, which is the rate of flow of electric charge, not potential difference.
• Currents: "Currents" is a term for the flow of charge, not a unit. The unit of current is the ampere.
• Watts: Watts are the unit of power, which is the rate of energy transfer or consumption, not potential difference.

So, potential difference is measured in volts.

Answer:

A. volts
