Question:

What happens to the quality factor in an LCR circuit if the capacitance is made five times?

Options:

becomes 2.5 times

becomes 25 times

becomes inverse \(\sqrt {5 }\) times

stays the same

Correct Answer:

becomes inverse \(\sqrt {5 }\) times

Explanation:

Quality factor :Q = [1/R] \(\sqrt {L/C }\)

Q ∝ 1/\(\sqrt { C}\)
