Question

a resonate circuit has an external Q factor 2 and an unloaded Q factor of 4. The loaded alpha factor is

Answer 1

Answer:

The “Q” stands for quality. It's the ratio of the inductance L to the resistance R of a coil at a given frequency and this defines the efficiency of inductor. The higher Q factor of the inductor, the closer the inductor to be ideal without losses.

i hope it's help to you

Answer 2

Answer:

quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. ... Q = Pstored/Pdissipated = I2X/I2R Q = X/R where: X = Capacitive or Inductive reactance at resonance R = Series resistance.
