Which one of the following is NOT correct?

Options

A. Dimensional formula of thermal conductivity (K) is `M^(1)L^(1)T^(-3)K^(-1)`
B. Dimensional formula of potential (V) is `M^(1)L^(2)T^(3)A^(-1)`
C. Dimensional formula of permeability of free space `(mu_(0))` is `M^(1)L^(1)T^(-2)A^(-2)`
D. Dimensional formula of RC is `M^(0)L^(0)T^(-1).`

Answer

D

Explanation

`RC` is called time constant of `RC` circuit and has dimensional formula `[M^(0)L^(0)T]`
So cannot choice is `(d)`.
