A coil of inductive reactance has a resistance of . It is placed in series with a condenser of capacitive reactance . The combination is connected to an . source of volts. The power factor of the circuit is.
Step1: Given data.
Inductive reactance,
Resistance,
Capacitive reactance,
Step2: Finding impedance of the circuit.
We know that,
Where, is the impedance of the circuit.
Since,
….
Step3: Finding power factor of the circuit.
Also, we know that.
Power factor
Hence, option A is correct.
