Question: The resonant frequency of a circuit is f. If the capacitance is made 4 times the initial values, then the resonant frequency will become [RPET 1996]
Options:
A) f / 2
B) 2f
C) f
D) f / 4
Show Answer
Answer:
Correct Answer: A
Solution:
$ f=\frac{1}{2\pi \sqrt{LC}} $
Þ $ f\propto \frac{1}{\sqrt{C}} $
