The dimensions of resistance are the same as (where $h$ is the Plank's constant and $e$ is the charge)

Options:

Answer:

Solution:

Resistance, $R = \frac{V}{i} = \frac{W}{q i}$

$= \frac{[{M L}^{2} T^{- 2}]}{[A^{2} T]}$

$R = [{M L}^{2} T^{- 3} A^{- 2}]$

$[\frac{h}{e^{2}}] = \frac{[{M L}^{2} T^{- 1}]}{{[A T]}^{2}}$

$= [{M L}^{2} T^{- 3} A^{- 2}]$
