A 6 pole round rotor 3 phase star connected synchronous machine has the following test results:Open circuit test: 4000 V line to line at 1000 rev/min, 50 A rotor currentShort circuit test: 300 A at 500 rev/min, 50 A rotor currentNeglect the stator resistance and core losses, and assuming a linear open circuit characteristic, calculate:(a) the machine synchronous reactance at 50 Hz,(b) the rotor current required for the machine to operate as a motor at 0.8 power factor leading from a supply of 3.3 kV line to line with an output power of 1000 kW,(c) the rotor current required for the machine to operate as a generator on an infinite bus of 3.3 kV line to line when delivering 1500 kVA at 0.8 power factor lagging,(d) the load angle for (b) and (c), and sketch the phasor diagram for (b) and (c).
Find the impulse response fpr the filter? How many nonzero terms does the impulse response contain?
A transconductance amplifier with Ri = 2 kΩ, Gm = 40 mA/V , and Ro = 20kΩ is fed with a voltage source having a source resistance of 2kΩ and is loaded with a 1kΩ resistance. Find the voltage gain realized (from the source internal voltage to the o..
A 10 uH inductor is connected to a circuit such that prior to t = 0 the current through the inductor is 10 mA. After t = 0 the current through the inductor is iL(t) = 10e^(-1000t) mA where t is time in seconds. a) Determine the expression for indu..
Explain how to use the knowledge of Structure-Property-Processing-Perfomance relationship to improve on a device based on semiconductivity. Name the device, describe how it is made, the principle guiding its function and application.
For each add instruction in this problem, assume that EAX contains the given contents before the instruction is executed, and give the contents of EAX as well as the values of the CF, OF, SF, and ZF flags after the instruction is executed.
Build a home security system circuit using this program. The system must include a door sensor,window sensor, smoke detector, water leak sensor, a motion detector.
Sketch the spectrum of this signal indicating the complex size of each frequency component. You do not have to make separate plots for real/imaginary parts or magnitude/phase. Just indicate the complex phasor value at the appropriate frequency.
g. What happened to all the power delivered to the resistors h. If the resistors are available with wattage ratings of 1/2 W, 1 W, 2 W, and 5 W, what minimum wattage rating can be used for each resistor
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
Zinc metal can be obtained from zinc oxide (ZnO), by reaction at high temperature with carbon monoxide (CO). ZnO(s) + CO(g) Zn(s) + CO2(g)The carbon monoxide is obtained from carbon.2C(s) + O2(g) 2CO(g)
The Problem: An Electric Heater is connected to a constant 250-V source and absorbs 1000 W. Subsequently, this heater is connected to a constant 210 V source.
Design a circuit that, given a 2-bit value, will light a LED corresponding to that value. One of four LEDs should be lit for each of the four possible input values (binary 0 through 3).
