JEE · NEET Previous Year Question

$An AC circuit has R = 100Ω, C = 2 μF and L = 80 mH, connected in series. The quality factor for the circuit is$

Topic: JEE PYQ

Answer: B. Full step-by-step solution below.

A $20$
B $2$
C $0.5$
D $400$

Correct answer: B

Solution

(b) Q = \frac{1}{R} \frac{L}{C} = \frac{1}{100} \frac{80 \times 10 ^{- 3}}{2 \times 10 ^{- 6}} = 2
