Answer:
Electric Resistance
Characteristic Notes
Standard Uncertainty ± 8.4×10-6 ohms
Metric (SI) Dimensions length2 × mass × time-3 × electric-current-2 These are the dimensions of the "electric resistance" quantity in SI units. There are other unit systems used in electromagnetics that may assign different dimensions.

Answer:
[M^1L^2T^-3A^-2]
Explanation:
According to ohm's law
V=IR
hence R=V/I
V=W/Q (Work done/Charge)
hence potential = [M^1L^2T^-2] / [AT]
[V]=[M^1L^2T^-3A^-1]
From the above equations
[R]= [M^1L^2T^-3A^-1] / [A]
= [M^1L^2T^-3A^-2]
