Consider the circuit shown in Figure.
a. Find an expression for the output voltage in terms of the source current and resistance values.
b. What value is the output impedance of this circuit?
c. What value is the input impedance of this circuit?
d. This circuit can be classified as an ideal amplifier. What is the amplifier type?
Problem 1. In a city full of sunshine there are a number of people. They can either drive their cars (to work or elsewhere), which can cause pollution and traffic jams, or they can ride bicycles (which is not problematic, given that in that city it a..
A 600V, dc shunt motor has an armature and field resistance of 1.5 ohm and 600 ohm, respectively. When the motor runs unloaded, the line current is 3A, and the speed is 1000 rpm.
A 75-kVA, 230-V/115-V, 60-Hz was tested with these results: Open-circuit test: 115 V, 16.3 A, 750 W; Short-circuit test: 9.5 V, 326 A, 1200 W Determine the equivalent impedance in high-voltage terms.
Construct the model shown in Figure 1 using Matlab Simulink. Calculate the efficiency of the motor under the loading condition of Section 4

A piston-cylinder device initially contains 1 m of nitrogen gas at 400kpa and 27 c. A resistance heater is turned on inside the cylinder which passes 70 kj of electricity to the nitrogen gas.
An Aluminum wire with a square cross section 2mm on a side is carrying a current of 1.5amps. Aluminum has a resistivity of 2.69*10^-6 ohm-cm and an atomic volume of 10cc/mol. Assuming aluminum has three free electrons per atom
Given a 4.0-nC charge on a 1.0 meter length of an inner cylindricalshell of radius a = 0.060 m, a -4.0-nC charge on a 1.0 meter lengthof an outer cylindrical shell of radius b = 0.077 m, & anεr = 9.0 dielectric in between the shells,
