EEE4115 Electrical Engineering principle, Assignment 2 Note: Except Question 1, All answers of voltage and current should be expressed in polar form Q1. A complex single phase ac power source is connected to a linear load. The voltage of the power source and the current flowing through the load are represented by the following time domain expressions, v=311sin(100)+120sin(300ft-10°)+50sin(500rt+45°) V iL=0.8sin(100-30°)+0.06sin(3007t+100.003sin (SoOnt-40) A a) Calculate the root means square value of the voltage source. (2 marks) b) Calculate root means square value of the load current. (1 mark) c) Calculate the real power of the load. (5 marks) d) Calculate the apparenat power. (2 marks) e) Calculate the power factor. (2 marks) f) Calculate the total harmonic distortion of the voltage and current. (2 marks) N
