Suppose that a new transmission line is to be added to the power system between Bus 1 and Bus 4. The line is rated at 200 MVA, and its series impedance is 0.008 + j0.064 pu. Assume that no capacitors have been added to the system, and determine the daytime and nighttime voltages at every bus. Did the new transmission line resolve the voltage problems?
The average power is not necessarily equal to the average current times the average voltage. To show this, find a voltage waveform and current waveform where each has a zero average value but their product has a non-zero value.
The objective of this laboratory is to determine the mathematical model of a DC motor which will be used in the subsequent labs to control the velocity and position of a physical system.
A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier.
Given a 1-phase 50 kVA 12.47 kV pf = 0.8 lagging static load a. Modeling the load as constant complex power, determine the correct value for S and I. b. Modeling the load as constant complex impedance, determine the correct value for Z and I.
The tray heats up according to ut = c2?u + h(x, y) where h(x, y) = 5(1 - sin(8πy)) and c2 = 10-4. Assume that u = 200 along each edge. Find the steady state temperature distribution of the tray.
A system initially consists of 3 lbm of a substance having specific internal energy u of 20 Btu/lbm, and 6 lbm of the same substance having an internal energy of 30 Btu/lbm. 150 Btu of energy is transferred as heat to this system
a conductor is connected to a battery and placed between two compasses. An electric current is then passed through the conductor. In what direction do the poles of the compasses point.
A "Mealy" synchronous sequential circuit has one input X and one output Z. An output Z = 1 occurs every time the total number of 1's received is "divisible by 3" AND the total number of 0's received is an even number greater than zero.
Tune PI Parameters, Question: Given are the facts that Gc and Gp(s) are in series and Gp(s) = (K * Km) / [s[(Ls+R)(Js+b) + K^2m)]].
What is the total number of electrons transported from the positive electrode to the negative electrode by the charge escalator from the time the battery is first used until it is completely dead?
