Formulas : Apparent Power , Real Power , Power factor

Formulas : Apparent Power , Real Power , Power factor
by

1 Answer

Answer :

Formulas:
Apparent Power = VI (Voltmeter reading x Ammeter reading)
Real Power = VI Cos Ф (Watt meter reading)
Power factor (Cos Ф) = Real Power / Apparent Power
Indicated Power = Observed reading X Multiplying factor
% Error = (Indicated Power –Actual Power) x100 /Actual Power
Actual Power = Voltmeter reading x Ammeter reading x Power factor
