Calculate the quality factor for the resistor.(a) inf(b) 0(c) 1(d) .7This question was posed to me during a job interview.The query is from Electric Motors topic in chapter Braking of Electric Motors of Electric Drives

Answer»

Correct choice is (b) 0

The best explanation: The quality factor is defined as the RATIO of the reactive power to the active power consumed. The resistor ALWAYS ABSORBS active power. The value of reactive power consumed is 0. Quality factor=0/P=0.
