Which of the following combinations of the physical quantity and their unit is NOT correct?

Correct option is D

The correct answer is (d) Electric charge - Volt. The SI unit of electric charge is the Coulomb, not Volt. Volt is the unit of electric potential or voltage.

Information Booster:

1. Resistance is measured in Ohm (Ω).
2. Force is measured in Newton (N).
3. Electric current is measured in Ampere (A).
4. Electric charge is measured in Coulomb (C).

Additional Knowledge:

• Volt: The unit of electric potential (1 Volt = 1 Joule/Coulomb).
• Ohm: The unit of resistance (1 Ohm = 1 Volt/Ampere).
• Newton: The unit of force (1 Newton = 1 kg·m/s²).
• Ampere: The unit of electric current.

Key Points to Increase Knowledge:

1. Understanding SI units is essential for solving physics problems.
2. The SI system (International System of Units) is globally accepted.
