NEET Physics Alternating Current Questions Solved


For the series LCR circuit shown in the figure, what is the resonance frequency and the amplitude of the current at the resonating frequency 

(1) 2500 rad – s–1 and 52A

(2) 2500 rad – s–1 and 5A

(3) 2500 rad – s–1 and 52A

(4) 25 rad – s–1 and 52A

(2) Resonance frequency

ω=1LC=18×103×20×106=2500rad/sec

Resonance current = VR=22044=5A
