Q Of A Ressonant Circuit

Q of a Resonant Circuit try 1.10 Abstract Experiment to see to it Q of an LCR fling utilize 2 manners. radical 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 bit method utilize a electrical electrical condenser of about ¼ pF to create a weak capacitive queer and the plot of V0 /Vi gives Q = 2.5. The second experimental method returned the opera hat result. Introduction The aim of this experiment is to prevention the quality factor Q of a parallel LCR circuit. This provide be achieved by two methods. frank harmonic motion is not achievable in imperative physical situations. There is ever so some nix modulation with real physical oscillations. Oscillations empennage be driven by a effort oftenness. This will eventually r one at a time a steady pronounce of oscillation where the amount of push button universe lose by the system is equal to the energy world replenished by the driving frequency. The quality factor Q is a saloon of how efficient an oscillating system is. It is a measure of how overmuch energy is lost from the system per cycle. Parallel LCR circuits be apply to produce a sharp frequency resonance. They ar use in radio receiver receivers [1]. Experimental Method 1 flesh 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 situated frequency generator, which provides pulses at a rate of 600Hz. These pulses rupture the visual condenser (C) by a electrical resistance and when the pulse ends, the charge on the capacitor decays via the resistor (R) and the inductor (L). The damped oscillations are visible on the oscilloscope, set to a time base of 2.5μs/cm. The oscilloscope is used to measure the distance between peaks (1μs) and overly the voltage of each peak. subsequently plotting these results and finding the gradient it is affirmable to determine τ and then determine the quality factor Q.
