L, C and R represent the physical quantities inductance, capacitance and resistance respectively. The combinations which have the dimensions of frequency are-

A

1/RC

B

`(1)/(sqrt(LC))`

C

R/L

D

L/R

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
(a,b,c) : RC is time constant similarly L//R is time constant hence reciprocal will be having the same dimensions as that of frequency . `(1)/(sqrt(LC))` is frequency of LC circuit . Hence options (a) , (b) and (c )are correct .
