Resonance in RLC Series circuits

[neduet]

Hello friends

Q1. Is that Resonance only happened in series circuit not in parallel,
which are consisting in R L C components?

Q2. what Is Q-Factor and is that Related with Resonance.

Please Must Explane this questions

thanks A lot

You can get resonances in both series and parallel circuits; there is no fundamental difference between the two.

The formal definition of the quality factor (Q) is given by the rate at which the resonator losses energy; from a more practical point of view it tells you how wide the resonance is (in frequency); for an ideal resonator the Q value is simply the resonance frequency divided by the width at the -3 dB point.
Or, in other words, a high Q value implies a narrow ("sharp") resonance.

[Edit] See the attached thumbnail solution to the RLC resonant circuit. Solve the quadratic equation and post your result and interpretation.
