Water is being heated in a vertical piston-cylinder device. The piston has a mass of 15 kg and a cross-sectional area of 120 cm^2. If local atmospheric pressure is 99.5 kPa, determine the temperature at which the water will start boiling.
A process has dynamics G(s)=1/(4s^s+s+1). Apply a unity negative feedvack controller of the form G.c(s)=1/(s+b). (a) Report the transfer function T(s) of the closed-loop system. (b) Report T(s) to 2nd order and report the reduced transfer function T..
An amplifier with 40 dB of small-signal open-circuit voltagegain, an input resistance of 1M-ohm ,and an output resistance10-ohm drives a load of 100-ohm .What voltage and power gains(expressed in dB) would you expect with the load connected
Discuss the different analog-to-digital converter (ADC) types and configurations. What is the purpose of the ADC. How do you interface to the different configuration
A Si (ni = 1 e+10 cm^-3, eps = 11.7) p-n junction is doped with NA = 5.2 e+18 cm^-3 and ND = 8.4 e+14 cm^-3. What reverse bias (the absolute value) should be applied to the junction, in order to achieve the maximum electric field of 3.89E+4 V/cm
A simple low-pass discrete-time filter is characterized by the following linear difference equation: y[n] = f y[n-1] +(1- f) x[n] , with 0 1 Draw and clearly label an adder-gain-delay diagram for the filter. using the same difference equation from a..
Two points with the coordinates P(2, 5, -1) and Q (3, 0, 4) exists in space. Find the vector form of PQ, the lenght of vector PQ, and the unit vector form of PQ
When room temperature exceeds approximately 82 degrees Fahrenheit, turn on a red LED. Use a PNP transistor to turn on one LED and an NPN transistor to turn on the other LED. Wire the LED's as parrellel loads. Build a bipolar power supply.
A calibrated RTD with ALPHA = 0.0041/°C, R = 306.5 Ohms at 20°C, and PD = 30 mW/°C will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100°C with a resolution of at least 0.1°C.
Consider an electron in a cubic crystal of a semiconductor material. Such an electron is free to move throughout the cubic volume of the crystal, but cannot escape outside the cube. It is trapped in a three-dimensional infinite potential well.
Calculate the maximum power that can be sent through an a=2cm , b=1cm air-filled waveguide at 12GHz such that dielectric breakdown does not occur. Assume that the dielectric strength of air at atmospheric pressure is 3x10^6 [V/m]
Construct a nontrivial resistive circuit with at least two loops and at least three resistors in each loop. Verify Kirchho's laws for this circuit both theoretically and empirically. Notice that this item is more open-ended.
A power company supplies 75 kW to an industrial load. The load draws 120 Arms from the transmission line. If the load voltage is 440 Vrms and the load power factor is 0.8 lagging, find the losses in the transmission line.
