The physical quantity having a unit of volt/ampere is _______________.

Correct option is D

​The correct answer is (d) resistance.

The physical quantity having a unit of volt/ampere is Resistance. This is because resistance (R) is defined as the ratio of voltage (V) across a conductor to the current (I) flowing through it, i.e.,

​$$R = \frac{V}{I}$$​​

Hence, the unit of resistance is Ohm (Ω), and it can be expressed as a volt per ampere.

Information about other options:

• A: Work is measured in joules, which is not related to volt/ampere.
• B: Current is measured in amperes, not volt/ampere.
• C: Charge is measured in coulombs, and while charge relates to voltage and current, it isn't measured in volt/ampere.

Information Booster:

• Resistance is a measure of how much an object opposes the flow of electric current. The higher the resistance, the less current flows for a given voltage.
