EEL 3211 Test 2 Solutions February 29, 2008 Time limit: 50 minutes. All Answers must include units. Most of these problems are one-liners for each part! One (1) 8.5’ by 11’ sheet of notes allowed. 1. (5 points) Three identical resistors are connected in a delta configuration to a three-phase line and dissipate a total power of 60 k-watts. If the same resistors are now connected in a wye configuration to the same three-phase determine the new power dissipated. The voltage across each resistor drops by a factor of 3 so the power drops by a factor of 3 to 20 k-watts 2. Three identical impedances are connected in a delta configuration across a 3-phase, 550 volt (line-to- line) source. If the line current is 10 amps, calculate a) (5 points) the current (magnitude) in each impedance and b) (5 points) the magnitude of each impedance. 3. (15 points) A 3-phase load is connected to a 440 volt line-to-line source and draws a current of 5 amps.
