The Correct Option is C
Solution and Explanation
Concept:
Electric potential difference represents the work done in moving a unit positive charge from one point to another.
Analysis of Units:
• Volt (Correct Answer):
• SI unit of electric potential difference.
• Named after Alessandro Volta.
• Defined as: \[ 1\,V = \frac{1\,J}{1\,C} \] where J = Joule and C = Coulomb.
• Ampere: SI unit of electric current.
• Watt: SI unit of power.
• Ohm: SI unit of electrical resistance.
