Calculate the quality factor for the R-C circuit if R=2 Ω and C=1 F.(a) 0.2(b) 0.4(c) 0.6(d) 0.5I got this question during an online exam.My question is based upon Regenerative Braking of DC Shunt Motors topic in portion Braking of DC Motors & Induction Motors of Electric Drives

Answer»

Correct CHOICE is (d) 0.5

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 and capacitor absorbs the reactive power. Quality factor=1÷RC=1÷2=.5.
