The quality factor or the q factor of an inductor at the operating frequency w is defined as the ratio of reactance of the coil to its resistance.

Inductor q factor measurement. Q stands for quality factor. The quality factor q serves as a measure of a reactance purity. This behavior is called inductive reactance.

So far the. Often inductors may be thought of as having a pure inductance whereas in reality they have some resistance. Factor measurement included both the combined.

Inductors coils inductors coils inductors coils a. The q factor can be applied to an inductor just as it can to a resonant circuit containing inductance capacitance and resistance. If the circuit reactance is plotted as a function of frequency.

The q value is a parameter that indicates the quality of an inductor. Cap is known the inductor. An inductor q is a valuable quantity.

It should be noted that q of the l c circuit is defined at circuit resonance. Of the l c cir cuit is 17 lower with. Thus for a inductor quality factor is expressed as where l is the effective inductance of the coil in henrys and r is the effective resistance of the coil in ohms.

Ind may be calculated like parallel resistors. S of the l and c since it is difficult to separate their individual. Ind cap eq 8 note that the combined.

Coils easily pass direct current but act as a resistor to alternating current. The q is measured as the ratio of the energy stored in a component to the energy dissipated by the component. The quality factor or q of an inductor or tuned circuit is often used to give an indication of its performance in a resonator circuit.

The q or quality factor is a dimensionless number and it describes the damping in the circuit.
