The unit of electrical resistance in the metre-kilogram-second system is called a/an ______.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ohm.
In the MKS (metre-kilogram-second) system, ohm (Ω) is the unit used to measure electrical resistance. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied across the points produces a current of one ampere.
