The Quality (Q) Factor of a capacitor is a unitless value which is equal to the capacitor''s reactance divided by the Equivalent Series Resistance (ESR) of the capacitor. As both reactance and ESR vary with changes in frequency, the Q value of a capacitor will also vary greatly with changes in frequency. Most applications do not have to consider the Quality (Q) …
A capacitor is one of the 3 passive electrical components : resistors, capacitors and inductors. A capacitor is basically a frequency dependant resistor. A resistor blocks all frequencies, however, a capacitor only blocks low frequencies. The rating of the capacitor (in Farads) determine which frequencies pass or not.

$begingroup$ @Andy Assuming "quality" is a numeric value to be used for ranking soil samples, then definitely the problem is one of discrete decisions: given a pair of attributes $(y_1, ldots, y_k)$ and $(x_1, ldots, x_k)$, which has better quality? You are correct that you need to know something about what quality is in order to create the ...
So it is must to improve PF above 0.95. Use of Capacitor Bank: A Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy. The resulting bank is then used to counteract or correct a power factor lag or phase shift. An inductive load.
