The quality factor Q determines the sharpness of resonance of an ac circuit. Obtain a relation that shows the dependence of Q on Resistance (R).

The sharpness of resonance is mean sured by Co-factor of the circuit :-Obtain an expression for Q-factor

What is Q- factor of an LCR circuit?

The current through an AC circuit depends on the magnitude of the applied voltage and impedance of the circuit:-Write any two factors on which the impedance of a series LCR ciruit depends.

Show that the relation R. in the set A of all points in a place given by R = {(P,Q): the distance of the points P from the point Q from the origin }, is an equivalence relation. Further show that the set of all points related to a point p != (0,0) is the circle passing through P with origin as centre.
