The quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒr /BW. Figure 2 Principle of induction heater and induction cooker. (1) and deduce the quality factor of the series resonant LCR circuit for different values of resistor. 3. Specifically, Q = w0 / 2a. Items 5 and 6 are the same as for the series resonant circuits, but the rest are quite different. Parallel resonance, which is more common in electronic practice, requires a more careful definition. Generally speaking, for an underdamped RLC system, the quality factor (Q) provides a comparison of the resonant frequency (w0) and the rate of decay or damping factor of the oscillating states (a). An LCR circuit, also known as a resonant circuit, tuned circuit, or an RLC circuit, is an electrical circuit consisting of an inductor (L), capacitor (C) and resistor (R) connected in series or parallel. It is approximately defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Compare them and draw conclusions. into above Eq. Electrical resonance is said to take place in a series LCR circuit when the circuit allows maximum current for a given frequency of the source of alternating supply for which capacitive reactance becomes equal to the inductive reactance. 1 0 m W. The damping of … A sinusoidal voltage of peak value 10 V is applied to a series LCR circuit in which resistance capacitance and inductance have value of 10ohm, 1µF and 1H respectively .find (i)the frequency which drives the circuit at resonance (ii)quality factor of the circuit. 0 V requires a power (p) = 0. A series resonant LCR circuit has a quality factor (Q-factor) 0.4. Resonance in AC circuits implies a special frequency determined by the values of the resistance, capacitance, and inductance.For series resonance the condition of resonance is straightforward and it is characterized by minimum impedance and zero phase. The sharpness of the peak is measured quantitatively and is called the Quality factor, Q of the circuit. The LCR Parallel Resonant Circuit. Find the quality factor of a circuit with capacitance C = 2. If the LCR series circuit is just one of the most useful circuits, here is the other one, the LCR Parallel Resonant Circuit! If R = 2 kΩ, C= 0.1μF,then the value of inductance is asked Jan 20, 2019 in Physics by kajalk ( 77.6k points) In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. 0 μ F and inductance L = 5. The LCR circuit analysis can be understood better in terms of phasors. The Q or quality factor is used with many RF tuned circuits or elements to indicate their performance in an oscillator or other form of resonant circuit. Table 3: Comparison table When resonance occurs in a parallel RLC circuit, a local current circulates between the inductor and the capacitor. The frequency response of the circuits current magnitude above, relates to the “sharpness” of the resonance in a series resonance circuit. Resonance. Make a comparison table for the estimated values of bandwidth and quality factor for different resistors. Values for quality factor are often seen quoted and can be used in defining the performance of an inductor, a capacitor or tuned circuit. 0 m H if the maintenance of undamped oscillations in the circuit with the voltage amplitude across the capacitor being equal to V m = 1. Simple formulas relate the losses and bandwidth to the Q. Electrical Resonance in Series LCR Circuit and Quality Factor Electrical Resonance in Series LCR Circuit. The bandwidth can be calculated as BW = f res /Q 4.
