Q Of A Ressonant Circuit

Q of a Resonant Circuit look into 1.10 Abstract Experiment to patch up Q of an LCR bend exploitation 2 rules. underlying LCR desexup: L = 31μH, C = 680 pF and R = 3kΩ. The first method is plotting ln Vm against Peak no and returned Q as 5x10-13. The hour method take a electrical cleverness of about ¼ pF to create a weak capacitive bilk and the plot of V0 /Vi gives Q = 2.5. The second experimental method returned the best result. Introduction The aim of this experiment is to class the quality factor Q of a parallel LCR circuit. This give be achieved by two methods. ingenuous harmonic motion is not achievable in authoritative physical situations. There is ever so some qualification pass with real physical oscillations. Oscillations underside be driven by a ride oftenness. This will eventually r singly a steady express of oscillation where the amount of vitality universe garbled by the system is equal to the energy world replenished by the driving frequency. The quality factor Q is a amount of how efficient an oscillatory system is. It is a total of how overmuch energy is lost from the system per cycle. Parallel LCR circuits are apply to produce a sharp frequency resonance. They are use in piano tuner receivers [1]. Experimental Method 1 radiation diagram 1 produces damped oscillations.

The circuit shown in Figure 1 is using L = 31μH, C = 680 pF and R = 3kΩ and is connected to the opinionated frequency generator, which provides pulses at a rate of 600Hz. These pulses sex the optical condenser (C) by a ohmic resistance and when the pulse ends, the charge on the capacitor decays via the resistor (R) and the inductor (L). The damped oscillations are viewable on the oscilloscope, set to a time base of 2.5μs/cm. The oscilloscope is used to measure the distance between peaks (1μs) and likewise the voltage of each peak. after plotting these results and finding the gradient it is contingent to determine τ and then determine the quality factor Q.
