Unit of `(CV)/(rho epsilon_(0))` are of
(`C =` capacitance, `V =` potential, `rho =` specfic resistence and `epsilon_(0) =` permittivity of free space)`

Explanation

As `C = (in_0A)/(d) and rho = (RA)/(I),`
where the symbols have their usual meaning,
therefore,
`(CV)/(rho in_0) = ((in_0A)/(d)) (V)/((RA//I)in_0) = (V)/(R ) = I`, the current
`(:. I, d "both represent distance")`
Therefore, the quantity represented is current.
