JEE · NEET Previous Year Question

$In LC parallel resonance circuit, choose the wrong statement.$

Topic: JEE PYQ

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

A $At resonance, current is minimum.$
B $At resonance, impedance is maximum.$
C $Resonance occurs when inductive and capacitive reactance is same.$
D $At resonance, resonant frequency = LC .$

Correct answer: D

Solution

(d) In LC parallel resonance circuit, at resonance X_{L} = X_{C} . \Rightarrow ωL = \frac{1}{ωC} \Rightarrow ω = \frac{1}{LC}
