In resonance condition, maximum current flows in the circuit
Current in LCR series circuit
i= 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= or
L=....(i)
Given,
ω=1000s−1,C=10µF=10×10−6F
Hence,
