Dimensions of (L)/(RCV) are

Answer»

`[A^(-1)]`
`[A^(-2)]`
`[A]`
`[A^(2)]`

Solution :`(L)/(R)` is the time constant of LR circuit, So `(L)/(R)` has the DIMENSION of time.
`:.[(L)/(R)]= [T]`
`:. "Charge" = "Capacitance" xx "Potential DIFFERENCE"`
`Q= CV :. [CV]= [AT]`
`:. [(L)/(RCV)]= [(T)/(AT)]= [(1)/(A)]= [A^(-1)]`
