King Fahd University of Petroleum & Minerals Electrical Engineering Department By: Dr. Chokri Belhaj Ahmed EE205-03 (042) QUIZ # 5 May 16-2005 Student Name ID Number A series combination of 150 resistor and a 20 nF capacitor is connected to sinusoidal voltage source by a linear transformer. The source is operating at a frequency of 500 krad/sec. At this frequency the internal impedance of the source is (5 + j16) . The rms voltage source is 125
