Question

L,C and R represent the physical quantities inductance, capacitance and resistance respectively. Which of the following combinations have dimensions of frequency?
A. `(t)/(RC)`
B. ` (R )/(L)`
C. `(1)/(sqrt(LC)`
D. `( c )/(L)`

Answer 1

Correct Answer - A::B::C
`Cp` and `(L)/(R )` both are time constent . Their unit is second
` (1)/(CR) ` and` ( R )/(L)` have the SI unit `("second") ^(-1)` Farther . Resonance frequency omega ` = (1)/(sqrt LC) `
