Applications of Q … Q factor for a coil is defined for a given frequency as the ratio of inductance L to the resistance R of a coil. The reciprocal value of quality is the loss factor (d). Q is inversely related to the range of frequency over which the system will exhibit resonance. The quality factor (Q) applies to any resonant circuit component; most often the quality factor of the coil determines the overall Q of the circuit. It is based on a ratio of the resonant frequency (i.e., “fc”) and its 3dB bandwidth (i.e., “B”). Q-factor, or quality factor, characterizes how under-damped a tuned LC resonator circuit of the antenna coil is. Circuit Diagram of Q-meter 2. Previous question Next question. Opposite of the Power factor is called the Q-Factor or Quality Factor of a Coil or its figure of merit. Q1. Q-meter is an instrument designed for measuring Quality factor (Q) of a coil as well as for the measurement of inductance, capacitance, and resistance of an electric circuit at radio-frequency. The higher the frequency of the alternating current, the higher the inductive reactance. For an intraocular coil, the Q factor must be enhanced in order to minimize the power loss in the device as well as to maximize the transfer efficiency of power telemetric link. \(Q=\frac{\omega L}{R}\) What is Q factor of coil? The sharpness of resonance increases with an increase in damping and decreases with a decrease in damping. However, although the coil is a conductor, the wire winding has certain resistance components (R). Q Factor = 1/ Power Factor=1/Cosθ= Z/R … (Where Power Factor Cosθ = R/Z) They are inversely proportional for the coil quality and are calculated from the ratio of reactance to ohmic resistance. Explanation: Greater coil area presents less opposition to the formation of magnetic field flux, for a given amount of field force (amp-turns). The enhancement of the Q factor can be achieved by increasing the number of turns (n) and the thickness of the conductive layer. Inversely related to the fraction of the energy in an oscillating system lost in one oscillation cycle. Generally, the quality of the coil will be better if its resistance R-value is low. For coils this refers to the ohmic losses of the coil-wire. "Q" stands for "Quality Factor". The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire. Contents hide 1. Q-meter is also known as RLC meter. Use this online inductor Q factor calculator to calculate inductor quality factor (Q factor) within the fractions of seconds. \(Q=\frac{F_{0}}{F_{3dB}}\) How does sharpness of resonance depend on damping? Question is ⇒ To increase Q factor of a coil, the wire should be, Options are ⇒ (A) long, (B) thin, (C) thick, (D) long and thin, (E) , Leave your comments or Download question paper. Quality Factor of Inductor: Every inductor has a small amount of resistance in addition to its inductance. To increase Q factor of a coil, the wire should be: A. Quality factor (Q) or coil Q-factor is a dimensionless unit for the losses of a coil, quartz, or a resonator. This behavior is called inductive reactance. Calculate the Quality Factor of a coil or capacitor with the Q Factor Calculator and learn on the go with the integrated live example The quality factor of a resonator is related to the bandwidth and is a measure of its resonant frequency response. All other factors being equal, greater coil area (as measured looking lengthwise through the coil, at the cross-section of the core) results in greater inductance; less coil area results in less inductance. Coils easily pass direct current but act as a resistor to alternating current. Technically, it is the ratio of the stored energy of the LC resonator circuit to discharged energy.
