Power Factor of LCR Circuit at Resonance
The power factor of an LCR circuit at resonance is equal to 1.
Explanation
- At resonance, the inductive reactance (XL) is equal to the capacitive reactance (XC) in an LCR circuit.
- This results in the total impedance (Z) of the circuit being purely resistive, as the inductive and capacitive components cancel each other out.
- In a purely resistive circuit, the power factor is equal to 1, indicating that the voltage and current are in phase.
- This means that all the power supplied by the source is being consumed by the circuit, with no reactive power being exchanged.
- Therefore, at resonance, the power factor of an LCR circuit is 1.
In conclusion, the power factor of an LCR circuit at resonance is 1, as the circuit behaves like a purely resistive load with no reactive power exchange.
