To find series resonance, choose Wuhan UHV. Difference between series and parallel resonanceIn a series circuit of resistors, capacitors, and inductors, the phenomenon of power supply, voltage, and current being in phase occurs, which is called series resonance. Its characteristics are: the circuit is purely resistive, the power supply, voltage, and current are in phase, the reactance X is equal to 0, and the impedance Z is equal to the resistance R. At this time, the impedance of the circuit is the smallest and the current is the largest, which may generate high voltage on the inductor and capacitor that is many times larger than the power supply voltage. Therefore, series resonance is also known as voltage resonance. The resonance voltage is superimposed with the original voltage, and parallel resonance: In parallel ci
