Question

The SI unit of resistance is:

• A. ampere
• B. watt
• C. ohm
• D. volt

Hint:

Ohm’s law: \( R = V/I \) defines resistance in terms of voltage and current.

Answer 1

The Correct Option is C

The SI unit of electrical resistance is the ohm (\(\Omega\)). It is defined by Ohm’s law as: \[ R = \frac{V}{I} \] where \(V\) is voltage and \(I\) is current. Thus, the correct answer is \( \mathbf{(C) \text{ohm}} \).
