# Dimensions of '$ohm$' are same as (where $h$ is Planck's constant and $e$ is charge)

$\dfrac {h}{e^2}$

##### SOLUTION
'ohm' is the unit of resistance and having dimension $=[ML^2T^{-3}A^{-2}]$
From option C $\Rightarrow \dfrac {h}{e^2}=\dfrac {ML^2T{-1}}{(AT)^2}=[ML^2T^{-3}A^{-2}]=Resistance (ohm)$
