what is sharpness of resonance and graph between current and frequency for two different series lcr circuits
Asked by HARPRIYA | 05 Sep, 2017, 08:44: PM
answered-by-expert Expert Answer
- The sharpness of resonance is defined by the Q factor.
- Q factor is a dimensionless parameter that indicates the energy losses within a resonant element which could be anything from a  mechanical pendulum, an element in a mechanical structure, or within electronic circuit such as a resonant circuit.
- In particular Q is often used in association with an inductor.
- The sharpness of resonance is related to how quickly the energy of the oscillating system decays.
- The below is the graph between current and frequency for series lcr circuits, with
sinusoidal steady-state analysis that is regulated at R = 1 Ω, C = 1 F, L = 1 H, and V = 1 V.

An inductor, a capacitor and a resistor are connected in series across an ac source of voltage. If the frequency of the source is decreased gradually. the reactance of: (a) both the inductor and the capacitor decreases. (b) inductor decreases and the capacitor increases. (c) both the inductor and the capacitor increases. (d) inductor increases and the capacitor decreases.
