NEET Exam Model Paper 10

In resonance condition, maximum current flows in the circuit
Current in LCR series circuit
i=

V

√R2+(XL−XC)2

Where V is rms value of current, R is resistance,XL is inductive reactance and XC is capacitive reactance
For current to be maximum, denominator should be minimum which can be done, if XL=XC
This happens in resonance state of the circuit, i.e.,
ωL=

1

ωC

or L=

1

ω2C

....(i)
Given,Hence,
