If L and R are respectively the inductance

Your Ultimate Guide to JEE & NEET Question Solutions

If $L$ and $R$ are respectively the inductance and resistance, then the dimensions of $\frac{R}{L}$ will be

A

${T^2}$

B

$T$

C

${T^{ - 1}}$

D

${T^{ - 2}}$
If $L$ and $R$ are respectively the inductance and resistance, then the dimensions of $\frac{R}{L}$ will be
$L/R$ is a time constant so $(R/L) = {T^{ - 1}}$
