Write a MATLAB program for the system of Example 2.5 such that the voltage magnitude of source 1 is changed from 75 percent to 100 percent of the given value in steps of 1 volt. The voltage magnitude of source 2 and the phase angles of the two sources is to be kept constant. Compute the complex power for each source and the line loss. Tabulate the reactive powers and plot Q1, Q2, and QL versus voltagemagnitude jV1j. From the results, show that the flow of reactive power along the interconnection is determined by the magnitude difference of the terminal voltages.
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication.
What is the minimum number of bits required to represent each of the following decimal numbers: 10, 1000, 100,000, and 1,000,000?
In the "far field" region, show that the electric field intensity of a linear electric quadrupole decays much faster in space than 1/R3 for the electric field intensity produced by an electric dipole and 1/R2 for an electric monopole.
Briefly discuss the source of solar energy and the processes involved by which the earth receive 5.7kWh/m^2/day over the entire surface. If it becomes possible to simulate the same process on earth
A meta dyne with a uniform air gap is driven at constant speed with a constant dc voltage applied to the q brushes the stator is unexcited. Determine the current in the two circuit and the voltage between the q brushes. what driving torque will be..
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
if the equation for a mesh current is done and the current comes out negative, with the assumed clockwise direction. does that mean that the current is actually going in the opposite direction
