Definition and Calculation Method of Power FactorPower Factor (PF) is a crucial parameter that measures the phase difference between voltage and current in an AC circuit. It represents the ratio of actual consumed active power to apparent power, reflecting the efficiency of electrical energy utilization. When there is a phase difference between voltage and current, the power factor is typically less than 1.1. Definition of Power FactorThe power factor is defined as: Active Power (P): The actual

Significance of Form Factor and Crest FactorForm Factor (FF) and Crest Factor (CF) are two key parameters used to describe the characteristics of alternating current (AC) signals.

The Significance of Series ResonanceSeries resonance is a special phenomenon that occurs in a circuit consisting of an inductor L, a capacitor C, and a resistor R connected in series. When the frequency of the circuit reaches a specific value, the reactance of the inductor and capacitor cancel each other out, resulting in the minimum total impedance and maximum current in the circuit. Series resonance plays a significant role in various fields such as radio communication, filter design, oscillat
