Question 1 [10 marks] A single-phase 50 Hz source supplies power to a motor load through a distribution line with an impedance of 0.185 + j0.321 . The terminal voltage of the motor is 230 V. The power drawn by the motor is 5 kW at a power factor of 0.7 lagging. Calculate the following. (a)The magnitude of source voltage. (b)The power lost in the distribution line. (c)The capacitance that should be connected in parallel to the motor to improve the power factor at motor terminals to unity. Assume the motor terminal voltage to

Question 2 [10 marks] A 3-phase, Y-connected source with a phase voltage of 120V feeds power to a 3-phase, ∆-connected load through distribution lines having the impedance of 0.5 + j1.4 Ω /phase. The load impedance is 118.5 + j85.8 Ω /phase. Determine the following. (a) The magnitude of distribution line current. (b) The magnitude of phase current of the load. (c) The magnitude of line voltage at the terminals of the load. (d) The total average power delivered to the load....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
