definition quality factor of inductor
Hi,
after reading a lot of papers, I am totally confused by the definition of quality factor of inductor. That is , should we take the electric energy that is inevitably stored in a real inductor into the account? if so should that form of energy be added to or subtracted from the dominant magnetic energy stored in the inductor. If the former is the correct definition, we should get the same definition of Q of an inductor as that of a resonator, If the latter is correct, we get the commonly used formula Q = -Im(y11)/Re(y11).
Thanks.
