Question

what is quality factor and power factor.explain .​

Answer 1

Answer:

QUALITY FACTOR : The quality factor or Q-factor of a coil is defined as the ratio of impedance of the coil to its resistance .It is also defined as, Q=2*3.141[(Maximum energy stored per cycle)/Energy dissipated per cycle)] The quality factor at resonance,that is at resonant frequency fr is, Q=(2*3.141fr.L)/R.

POWER FACTOR : In electrical engineering, the power factor of an AC electrical power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. ... Apparent power is the average product of current and voltage.
