The power supplied to a three-phase induction motor is 32 kW and the stator losses are 1200 W. If the slip is 5%, determine (a) the rotor copper loss, (b) the total mechanical power developed by the rotor, (c) the output power of the motor if friction and windage losses are 750 W, and (d) the efficiency of the motor, neglecting rotor iron loss.
let x be a random variable that is exponentially distributed with agt0 i.e. fxx aexp-ax for xgt0 and fxx0 for xlt0.
Bandwidth, In a given communications system, one signaling element is used to represent 64 bits. The required data rate is 1.789 Mbps.
Determine which waveform in each pair is lagging: a) 6 cos(100πt-1000) and -6 sin (2π60t+1300)b) cos(10t-1000) and - cos(t-1000) c) cos (50πt - 1000) + cos (50πt - 200) and 9 cos (100πt - 200)
Design a first order activehigh pass filter with a high frequency gain of 10 and a cut-offfrequency of 400 Hz. Choose C = 100 nF.Determine Ri and Rf. and Design a Sallen-Key low passfilter with Q = 4 and fo = 5000 Hz.
If the SNR must be greater than 40 dBm, how far backed-off must the amplifier operate. Assume noise comes from a third-order intermodulation between two interferers with the same power level as the wanted signal.
Design channel coding performance simulator that compares two channel coding technique X and Y . You can provide pseudocode or block diagram of the simulator.
A series circuit consisting of a 0.398-henry inductor and a 212-µF capacitor is connected to a 125-volt variable frequency source. At what frequency will the circuit take a lagging current of 2.5 A a leading current of 2.5 A
In animation programs, special effects are achieved by changing the properties of objects. What instruction is used to change the opacity and color properties of objects in the Zeus example world?
Notice that when C begins sending, the signal due to the frame from A has not reached station C yet. If it reached, station C would not send it. How many bits from station C have already been sent when it hears the signal from A
Find the primary voltage and voltage regulation when the transformer is operating at full load 0.8 power factor lagging and 240 V. Find the primary voltage and voltage regulation when the transformer is operating at full load 0.8 power factor leadin..
Find the max instantaneous power delivered by the source, dissipated by R, and absorbed by L. What are the smallest instants (t > 0) at which these maxima occur.
