Voltage and Current in Series Resonant Circuit

Voltage and Current in Series Resonant Circuit: The variation of impedance and current with frequency of Voltage and Current in Series Resonant Circuit is shown in Fig. 8.7. At resonant frequency, the capacitive reactance is equal to inductive reactance, and hence the impedance is minimum. Because of minimum impedance, maximum current flows through the circuit. …
