Units of Resistance
Asked by Aniket Sharma · 2 years ago
What is the SI unit of resistance, and how does it relate to the dimensional formula?
1 Answer
The SI unit of resistance is ohm (Ω). One ohm is defined as the resistance that allows one ampere of current to flow when one volt is applied across it. This definition aligns with the dimensional formula [M L2 T-3 A-2], as it incorporates mass, length, time, and electric current, which are the base quantities represented in the formula.
