Q factor
A measure of the quality of an electric circuit; the ratio of the reactance to the resistance.
In general if one decides to find the energy stored in a LTI inductor that has initial current in a specific time between and can use this: : Q factor An ideal inductor would have no resistance or energy losses. Source: Internet
Operating at a lower frequency, IF filters can give narrower passbands at the same Q factor than an equivalent RF filter. Source: Internet
The energy dissipated in the spark also reduces the Q factor and the output voltage. Source: Internet
