A 1 MVA three-phase 6,600/400V delta/star connected transformer has the following parameters per phase.
HV side: R1 = 1.307 ohms X1 = 5.228 ohms
LV side: R2 = 0.0016 ohms X2 = 0.0064 ohms
(a) Calculate the per unit impedance of the transformer using base values of 1 MVA and 400 V. (and .)
A transducer produces a sinusoidal waveform with an amplitude of 2.5 VPK and a DC offset of 0 VDC. The ADC input signal range is 0 V to 5 V. Describe the signal conditioning circuit that is needed to use the full-scale range of the ADC.
A program has a char variable fruit that has been assigned a value. Write a switch statement that outputs "Apple" if the variable contains lower or upper case 'a', "Banana" if it contains lower or upper case 'b', or "Invalid Input" for any other v..
The average output load voltage
For use in a liquid crystal display, you want an electrode that is transparent to all visible light. You decide to use a doped semiconducting oxide with a mobility of 10^(-2) m^2/V-s. What is the maximum conductivity you can expect from your oxid..
Explain why the low value (0) for the 'output' of a digital logic gate is lower than the low value for the 'input' of a digital logic gate (This is the case for CMOS and Bipolar logic). Look at a specsheet.
Model the actual resistive value R0 of a resistor marked as 100 ? with a 5% tolerance as a uniform random variable R0 over the range [95, 105] ?.
Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2,000 Hz. In order to ensure the filter stability, set the poles at 0.96 radial distant from the origin
a conducting rod having a mass density 2 kgm is suspended by two flexible wires in a uniform magnetic field which
If each packet carries 1000 bitsof data, the distance between the sender and receiver is 5000km,link speed is 1Mbps, and the propagation speed is2x108 m/s. Assume no data or control frame is lostor damaged. Ignore transmission time for ACK.
Explain what happens inside a semiconductor device when it is operating in enhancement mode.
An electron is confined inside a potential well with infinite walls. The width of the of the wells = 5nm. What is the probability of finding a electron within 1nm from either wall if the electron is at: A)the lowest energy level B). the 2nd lowest ..
It is believed that the etching may alter surface crack geometry (i.e., reduce crack length and increase the tip radius). Compute the ratio of the original and etched crack tip radii for an eightfold increase in fracture strength if two-thirds of ..
