A series 
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 [NEET 2020]
Text Solution
Verified by ExpertsThe correct answer is:
B
For 
circuit, phase difference,
When L is removed, then 
… (i)
When C is removed, then 
… (ii)
From Eqs. (i) and (ii), we get
Impedance,
Power factor,
