Question
Round off answers up to the 4th decimal place. Answers should be in rectangular and in polar form Draw circuit diagrams. 1) A circuit with impedance Z = 8 – j6 n has an applied phasor voltage 70.7 4 – 90°V. Obtain the complete power triangle. 2) The addition of a 20 – kvar capacitor bank improved the power factor of a certain load to 0.90 lagging. Determine the complex power before the addition of the capacitors, if the final apparent power is 185 kVA.
