For the LCR circuit, shown here, the current is observed to lead the applied voltage. An additional capacitor C', when joined with the capacitor C present in the circuit, makes the power factor of the circuit unity. The capacitor c', must have been connected in
A
series with C and has a magnitude 
B
series with C and has a magnitude 
C
parallel with C and has a magnitude 
D
parallel with C and has a magnitude 
Text Solution
Verified by ExpertsThe correct answer is:
D
Since power factor has to be made 1.
Effective capacitance should be increased thus connecting in parallel.
Resonance condition
in parallel.
