A series LCR circuit is connected to an ac voltage source. When L is removed from the circuit, the phase difference between current and voltage is 
. If instead C is removed from the circuit, the phase difference is again 
between current and voltage. The power factor of the circuit is:
Text Solution
Verified by ExpertsThe correct answer is:
NOT AVAILABLE
When L is removed,
…(i)
When C is removed,
…(ii)
From (i) and (ii), X L = X C
Since, X L = X C , the circuit is in resonance.
Z=R
Power factor
