the rms voltage of a balanced 3 phase Y connected source is 110 volts at 60Hz. it is connected to a balanced Y Load by 3 distribution lines with an impedence on each line z=1+j2. the load impedence is z=19=j28 per phase. the phase sequence is acb. use the a sequence as a reference
a) need the a phase circuitb) calculate IaA, IbB, IcCc) find voltage VAN at the loadd) find the voltages VAB, VBC, VCA at the load, and their values in time domain
Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
Discuss the advantages of transforming time-domain circuits into the corresponding frequency domain. How does this change the way circuits are analyzed
Design a combinational circuit that takes two 3-bit binary numbers a2a1a0 and b2b1b0 and generates Modulo-8 addition. Recall that the MOD operation produces the remainder value in an integer division. (Note: Do not use any CAD tool.
An industrial isolation transformer has a power rating of 1.0 kVA at 240 VAC. Identify the nominal turns ratio (nsec/ npri). Calculate the rated current of the secondary winding.
a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier.
The A/D converter has internal memory that can store up to 4x106 discrete samples. What is the maximum number of cycles of a 25 MHz analog sinewave that can be stored in the A/D converter's memory.
A transmission line segment with Zo=50 Ohms and of length l is terminated at a load resistance of RL that can be varied. Sketch the input impedance Zin as a function of RL if (a) l=(wavelength/4) and (b) l=(wavelength/2).
Determine the relative permittivity of the dielectric, the maximum and minimum electric field intensities in medium 1 and the electric field intensity in medium 2.
The electric motors unmanned drones use transformers to produce sufficient current to move the flight surfaces. Due to the weight restrictions of the vehicle, the transformers use a ceramic rather than iron, the ceramic has a permeability of mu = 4..
Design a second stage (Rin, Rout, and Av) to meet these specifications: a) the two-stage amplifier has an open circuit voltage gain of 120 b) the open circuit voltage gain of the second stage must be in the range 50-100
a machine processor address a maximum 2^24 bytes of memory. What is the maximum number of 32 bit words that can be store in memory.
What happens to an ECG signal when a triggered average is applied I can see from the graphs that the peaks directly before and after the triggered peak become more and more blurry, but I don't understand
