Asked by anirban71d 26th February , 1: Figure below This also affects the broadness of the curve. Impedance peaks at resonance. Call us Toll Free to speak to our academic expert. Below resonance it looks capacitive. Parallel resonant response varies with Q. A low resistance, high Q circuit has a narrow bandwidth, as compared to a high resistance, low Q circuit.
In a parallel resonant circuit, current through L or C is Q times the total applied current. Continue , I understand this browser is not compatible. Your Answer has been posted successfully. Impedance is at a minumum at resonance in a series resonant circuit.

Figure below Parallel resonant circuit: Resonant circuits are used to respond selectively to signals of a given frequency while discriminating against signals of different frequencies. If the response of the circuit is more narrowly peaked around the chosen frequency, we say that the circuit has higher “selectivity”.

A “quality factor” Q, as described below, is a measure of that selectivity, and we speak of a circuit having a “high Q” if it is more narrowly selective. Above or below resonance, impedance increases.

Our formula is correct for a small R in series with L. Enter your valid mobile number below.
Resonant RLC Circuits
This is correct for a large value of R in parallel with C and L. Quote of the day. The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are degrees apart in phase. Figure below Below the resonant frequency, the series resonant circuit looks capacitive since the impedance of the capacitor increases to a value greater than the decreasing inductive reactance, leaving a net capacitive value.
Above resonance it appears inductive.
What is meant by sharpness of resonance in a series lcr circuit?

The bandwidth of the parallel resonant response curve is measured between the half power lcg. This content is available for subscribed users only.
The sharpness of the minimum depends on the value of R and is characterized by the “Q” of the circuit.
