Explanation
At resonance in a series LCR circuit, the inductive reactance (XL) equals the capacitive reactance (XC), so the impedance (Z) is equal to the resistance (R).
Z = R
The power factor (PF) is the ratio of the real power (P) to the apparent power (S):
PF = P / S = R / Z
Since Z = R at resonance, the power factor is:
PF = R / R = 1
