RLC Series CircuitThe RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.

RLC Series ImpedanceWhen exploring the values for real circuits, it is easy to find examples where both V_{L} and V_{C} are larger than the resultant voltage V. This can occur because these voltages V_{L} and V_{C} act 180° out of phase with each other. You can visualize this from the phasor diagram by seeing that both V_{L} and V_{C} can be large and that they exactly cancel each other at resonance. Default values will be entered for unspecified parameters, but all component values can be changed. Click outside the box after entering data to initiate the calculation.
