The quality factor or "Q" of an inductor (links to http://www.mw0llo.com/inductors.aspx) of given inductance and resistance at a certain frequency is given by:

MathML formulaFormula ImageStraight text formula
Q = 2πfL R Q of an inductor of given inductance and resistance at a certain frequency Q = Inductive reactance XL / R = 2πfL / R

Where:

f = frequency, Hertz

L = inductance, Farads

R = resistance, Ohms

Summary: watch, in the eyes of different people, the scene is not the hublot replica watches same, some people say that the watch is just a plaything, some people say that the watch is a handicraft, has the connotation, there are people who have a watch as a business, is a commodity, but for the majority of game player, is to spend real money to buy watches the replica watches personal and exclusive products, it is not only a plaything, nor the daily consumables, not a rolex replica commodity, it is like clothes, shoes, car, is a part of life, is a part of love, is to let oneself have a part of quality.
