The power factor of an LCR circuit at resonance is 1.
At resonance, the inductive reactance (XL) and capacitive reactance (XC) in the circuit cancel each other out, resulting in a purely resistive circuit. This means that the circuit impedance (Z) is equal to the resistance (R) of the circuit.
The power factor (PF) of an AC circuit is defined as the ratio of the real power (P) to the apparent power (S). It indicates the phase relationship between the voltage and current in the circuit.
In a purely resistive circuit, the voltage and current are in phase, which means that the power factor is 1. This is because the current flows through the circuit in the same direction as the voltage, resulting in no phase difference between them.
At resonance, the LCR circuit behaves as a purely resistive circuit. Therefore, the power factor of the LCR circuit at resonance is 1.
To summarize:
- At resonance, the inductive reactance (XL) and capacitive reactance (XC) cancel each other out, resulting in a purely resistive circuit.
- In a purely resistive circuit, the voltage and current are in phase.
- The power factor of a circuit is 1 when the voltage and current are in phase.
- Therefore, the power factor of an LCR circuit at resonance is 1.

The power factor of LCR circuit at resonance isa) ...
At resonance R=Z
Power factor = R/Z
Therefore power factor = 1
Power factor = R/Z
Therefore power factor = 1
