Fig. 17. Source emf and voltage across capacitor and inductor as functions of time. Fig. 18. Circuit currents as functions of time. Fig. 19. Power supplied by source and power dissipated in the output resistance. By changing the parameters, it easy to verify: The source current is minimum at the resonance frequency iS as the individual branch currents and cancel and the iC IL total circuit impedance |Z| is a maximum. The source current is in phase with the source emf iS vS.
