The unit of resistance is ____________.

Correct option is C

The correct answer is (c) Ohm.
The unit of resistance is the ohm (Ω), named after the German physicist Georg Simon Ohm. It is the resistance that allows a current of one ampere to flow when a potential difference of one volt is applied across the conductor.
Information Booster

• Ohm's Law: $$R = \frac{V}{I}$$​ where R is resistance, V is voltage, and I is current.
  
• ​Formula for Resistance: $$R = \rho \times \frac{L}{A}$$​ where ρ\rhoρ is resistivity, L is length, and A is the cross-sectional area.

Units:

• Ampere (A): Unit of electric current.
  
• Coulomb (C): Unit of electric charge.
  
• Volt (V): Unit of electric potential.
