Homework Statement

What does Q-factor and Dynamic resistance of a parallel resonance circuits mean?

Homework Equations

The Attempt at a Solution

In general, their performance is measured by a dimensionless parameter named quality factor Q, which characterizes the sharpness of the resonant peak. The higher the quality factor the sharper is the peak and the better is the resonator.

and Dynamic resistance of a parallel resonance circuits mean?

This would be the real component of the circuit's impedance at resonance.

 

[rude man]

Q is always 2pi times the stored energy within a cycle divided by the energy dissipated within that cycle, assuming resonance. Always.

So compute this ratio for your parallel circuit.

Q can be defined for a component not in resonace with the rest of its circuit. But then the formula for Q is the same as though that component were part of a resonant circuit.
