In an LCR circuit, the capacitance is made one-fourth, when in resonance. What should be the change in inductance, so that the circuit remains in resonance?

Options:

Answer:

Solution:

For resonance

$ω = \frac{1}{\sqrt{LC}}$

for $ω$ to remain in resonance $L C$ should remain the same so if $C$ is made one-forth $L$ should be made $4$ times.
