Question

In an LC oscillator, if values of inductance and capacitance become twice and eight times, respectively, then the resonant frequency of oscillator becomes $x$ times its initial resonant frequency $\omega_0$ The value of $x$ is:

• A. $1 / 4$
• B. 4
• C. 16
• D. 1/16

Answer 1

Answer: (A)

$1 / 4$

Answer 2

The resonance frequency of LC oscillations circuit is
?0?=LC?1?
L?2L
C?8C
?=2L�8C?1?=4LC?1?
?=4?0??
So x=41?
