A computer power supply delivers 6A at 12V, 10A at -5V, and 12A at 5V. What is the power output of this supply?
A three phase generator is producing power for a balanced load. Each phase provides an rms voltage of 690 V and an rms current of 1000 A. The angle between the voltage and current in each phase is 20 degrees.
Design a Common Emitter amplifier with no bypass capacitor to obtain a voltage gain of -10 when Rin= 2k, Rload= 4k, VCC= 15V, VBE= 0.6V, and beta= 300. This amplifier requires an output swing of 4V peak-to-peak.
A power supply outputs 25Winto a load. The power supply input voltage is 115V and the inputcurrent is 0.5A. What is the effiecency of the power supply
four determinations of the pH of a certain solution are 7.90, 7.94, 7.91, and 7.93. Assuming normallity of determinations with mean mhu, standard deviation sigma, find: A. 99% confidence interval for mhu "u"
Obtain the power factor of a two-branch parallel circuit whre th efirst branch has Z1 = 2 + j4 ohms and the second Z2 = 6 + j0 ohms. To what value must the 6-ohm resistor be changed to result in the overall power factor of 0.90 lagging
What is the normal or average life expectancy of a Transformer ?
Dynamic microphone changes sound into an electrical signal - Determine the Thevenin Equivalent circuit as seen from terminals A and B in the sketch
Describe three methods of comparing techniques to improve the first swing electromechanical transient behaviour of such a generator.
