    What is Resonance of a Circuit ?

the condition in which an electric circuit or device produces the largest possible response to an applied oscillating signal, especially when its inductive and its capacitive reactance's are balanced.

   What is Q of a Resonance Circuit.

The Q, quality factor, of a resonant circuit is a measure of the "goodness" or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwidth, which is desirable in many applications. More formally, Q is the ratio of power stored to power dissipated in the circuit reactance and resistance, respectively.

  Resonance Circuits are used in AM/FM radios to select the the desired station/channel. Resonance Circuits are also used to block or prevent a group or single signal from propagating.
