PhysicsMediummultiple choice

$L, C$ and $R$ represent the physical quantities inductance, capacitance and resistance respectively. The combinations which have the dimensions of frequency are (JEE 1984)

Options:(select one or more)

Answer:

A, B, C

Solution:

$CR$ and $\frac{L}{R}$ are both time constants (units of second), so $\frac{1}{CR}$ and $\frac{R}{L}$ have the SI unit $(second)^{- 1}$ .
Further, the resonance frequency $ω = \frac{1}{L C}$ also has the dimensions of frequency.
$\frac{C}{L}$ does not have the dimensions of frequency.
