Question

i) State the condition undert which the phenomenon of resonance
occurs in a series LCR circuit
ii) Plot a graph showing variation of current with frequency of
ac source in a series LCR circuit
iii) At resonance what is the value of power factor in the case
of LCR series circuit ?

Shruti Kulkarni · Answer

i ) Resonance occurs when the inductive reactance will be equal
to the capacitive reactance in a LCR circuit
iii ) At resonance the value of power factor (cos fi) is 1 i e
it is maximum
