Question

Volt is the SI unit of

• A. electric charge
• B. specific resistance
• C. electric current
• D. None of these

Answer 1

The Correct Option is D

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 \( \mathbf{(4)} \).
