The Q factor of a capacitor, also known as the quality factor, or simply Q, represents the efficiency of a given capacitor in terms of energy losses. where Δω is the width of the resonant power curve at half maximum. The quality factor Q is defined by. The Q is a commonly used parameter in electronics, with values usually in the range of Q=10 to 100 for circuit applications. Since that width turns out to be Δω =R/L, the value of Q can also be expressed as. But the circuit “Q” factor is the inverse of Power factor, thus “Q” factor in both Pure Capacitive and Inductive Circuits are infinite (∞). Higher Q-factor values imply higher QEPAS signals [84]. Accordingly this is a component of the inductor resistance and will reduce the inductor Q factor. Quality Factor often called as Q factor is a dimensionless quantity to measure the quality of capacitor. The quality factor of a radiation type is defined as the ratio of the biological damage produced by the absorption of 1 Gy of that radiation to the biological damage produced by … Hence, when the first overtone mode of a QTF exhibits a quality factor higher than that of fundamental mode, a higher QEPAS signal is also expected. In order to calculate the Q, quality factor for an inductor, the formula … Q Factor. Q Factor in a Series RL Circuit In Series RL Circuit, Impedance (Z) = the inductive Reactance = X L = 2πfL, Therefore the Quality factor “Q” QTF#2, QTF#4, QTF#5 and QTF#6 have been employed in a QEPAS setup, operating both at the fundamental and first overtone mode [84, 104]. Formula : Quality Factor (Q) =2*Π*F*L / R Where, Π=3.1415929203539825 F=Frequency of Circuit L=Capacitance Value R=Resistance Value 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 = ƒ r /BW. Encyclopedia > letter Q > Q factor. Inductor Q factor formulas. You can calculate effective resistance R and effective reactance X of RLC circuit for a given frequency. Quality factor is the ratio of reactance and resistance. It represents how efficiently the energy stored in a capacitor be used in the electrical & electronic circuits. Then Q = X/R. • The quality factor increases with decreasing R • The bandwidth decreases with decreasing R By combining Equations (1.9), (1.10), (1.11) and (1.18) we obtain the relationship between the bandwidth and the Q factor. Category: optical resonators. German: Gütefaktor. Minimising the resistance effects reduces the losses and increases the inductor Q factor. Definition: a measure of the damping of resonator modes. 0 L B R Q ω == (1.19) Therefore: A band … Formula symbol: Q Units: (dimensionless number) How to cite the article; suggest additional literature. It's a ratio between capacitor's reactance (X c) and equal series resistance (ESR). Resonant circuit can be characterised by quality factor Q = P L + P C P l o s s w. Resonator losses can have different nature, including conductor losses, dielectric losses, radiation losses and others. Quality Factor.
