E xplain how frequency affects the reactance of an inductor. D escribe the basic properties of series RL circuits. E xplain the meaning of the Q , or merit , of an inductor.
C alculate the Q of an inductor.
D escribe how the Q of an inductor changes with the operating frequency. The Q of an inductor is the measure of its quality . The more 'perfect' the inductor, the higher its Q value. The Q of a coil is also known as the merit of a coil. A 'perfect' inductor would have a Q of infinity.
