The apparent power drawn by an A.C. circuit is 10 kVA and active power is 8 kW. The reactive power in the circuit is? Answer : The apparent power drawn by an A.C. circuit is 10 kVA and active power is 8 kW. The reactive power in the circuit is 6 kVAR. ...
In an alternator at lagging power factor the generated voltage per phase as compared to that at unity power factor? Answer : In an alternator, at lagging power factor the generated voltage per phase as compared to that at unity power factor must be more than terminal voltage. ...
In a synchronous generator delivering lagging power factor load (1) the excitation emf leads terminal voltage by the power angle (2) the excitation emf lags terminal voltage by the power angle (3) ... by the power factor angle (4) excitation emf lags the terminal voltage by the power factor angle Answer : In a synchronous generator delivering lagging power factor load the excitation emf leads terminal voltage by the power angle ...
Power factor of an inductive circuit is usually improved by connecting capacitor to it in? Answer : Power factor of an inductive circuit is usually improved by connecting capacitor to it in parallel. ...
Briefly explain how the power factor of an inductive circuit can be improved. Answer : As we know that power factor should be corrected to ensure that the current supplied is cost friendly. Meaning the power factor should be around one but not greater than one(0.8-0.9) in a ... an inductive circuit due to the inductive reactance which oppose the change of current in the ac circuit. ...
