Which of the following is the SI unit of electrical resistance ?
Ohm
Electrical resistance is defined by Ohm's law as \(R = \dfrac{V}{I}\), and its SI unit is the ohm (\(\Omega\)), named after Georg Simon Ohm.
Ampere is the SI unit of electric current, watt is the SI unit of power, and volt is the SI unit of potential difference — none of these measures resistance.
Therefore, the SI unit of electrical resistance is the ohm.
