Power factor is the cosine of the phase angle between voltage and current. In a purely resistive load, like a toaster, since the phase angle is zero, the power factor is 1. In a theoretically purely inductive or capacitive load, with the phase angle at 90 degrees, the power factor is 0. Power factor is also the ratio of apparent power versus true power, or watts versus volt-amperes.

Q factor is the quality factor. It is the reciprocal of band width. The lower your band width the more your q factor. In case of fine tuning actualy band width is adjusted to narrower changing the L of a coil and finaly the desired frequency is matched. Thus disturbance is reduced.

A coil of wire is an inductor. It's power factor should be very near zero. It will not be zero, since the wire has real resistance as well as inductance.

q factor means quality factor and is used to check the sharpness of resonance in the circuit.

Why in coil power factor is low?

A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.


Why current lagging in the coil?

The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.
