What is Q factor in inductance?
The quality factor or the Q factor of an inductor at the operating frequency ω is defined as the ratio of reactance of the coil to its resistance. 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.
How can Q factor of inductor be increased?
In order to increase the Q factor further, for the novel inductor, a patterned ground shield is used with optimized layout together.
How do you calculate Q factor capacitor?
Typical values for a good high frequency capacitor of a given value could run in the order of about 0.05 ohms at 200 MHz, 0.11 ohms at 900 MHz, and 0.14 ohms at 2000 MHz. The quality factor Q, is a dimensionless number that is equal to the capacitor’s reactance divided by the capacitor’s parasitic resistance (ESR).
How does quality factor increase inductor?
Thicker wires, and sometimes silver or silver plated wires may be used to reduce this and improve the overall inductor Q factor. Skin effect: The skin effect affects the inductor Q because it has the effect of raising the resistance.
What is the relation between Q factor and power factor?
As we know that the Power in Pure Capacitive and Inductive Circuits are Zero. Thus the Circuit Power factor is also Zero. But the circuit “Q” factor is the inverse of Power factor, thus “Q” factor in both Pure Capacitive and Inductive Circuits are infinite (∞). = Z/ R → = XC /R → = (1/2πfrC) /R → = 1 / 2πfrCR.
What is Q factor give its physical significance?
Significance : Q factor determines the sharpness of the resonance curve, if Q is high, the resonance curve is sharper and the energy lost by the circuit is less. Sharpness: Sharpness of a AC circuit is related to the Q factor. IF the sharpness is more we get a clear effect in the system and resistance is less.
