Volt is the SI unit of
Updated On: Apr 5, 2025
- electric charge
- specific resistance
- electric current
- None of these
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The volt (V) is the SI unit of electric potential difference or voltage. It measures the work done per unit charge to move a charge between two points in an electric field. None of the given options directly correspond to this definition.
- (1) Electric charge: The SI unit of electric charge is the coulomb (C).
- (2) Specific resistance: The SI unit of specific resistance (resistivity) is ohm-meter (Ω·m).
- (3) Electric current: The SI unit of electric current is the ampere (A).
Final Answer: The correct answer is \( \mathbf{\text{None of these}} \), which corresponds to option \( \mathbf{(4)} \).
