1. Why is the QR method not suitable for the eigenvalue analysis of large-scale electrical power systems?
2. What is the critical eigenvalue? What methods are there for calculating critical eigenvalues of large-scale electrical power systems? What advantages and disadvantages are there for each method?
the electric field srength E due to an infinite line of chargeis given by E = λ/(2πrεo), where λ is the charge per unit length and r is the radial distance from the wire. a, show that this formular for E still has the units of N/C.
A single-phase power system is shown in Figure P3-1. The power source feeds a 100-kVA 14/2.4-kV transformer through a feeder impedance of 38.2 + j140 W. The transformer's equivalent series impedance referred to its low-voltage side is 0.12 + j0.5 ..
Design a common collector circuit using a npn silicon transistor having Beta=90 with Vcc=20 V The desired Q-point is Vce=14V and Ie=2mA
There are two charge distributions: one in a infinite plane of charge in x=-2 with a surface charge density of 3mC/m2, abd a infinite line of charge with a linear charge density of -3mC/m that goes through the points A(0, 0, 3m) and B(0, 3m, 0).
i want to find taylor series expansion of a gate charge function. the equation is gx 4.5e-12 - qdepl - betavds - vgs
A Common-Source amplifier utilizes a MOSFET with µnCox = 400µA/V2, W/L = 10, and VA = 10V. It is biased at ID = 0.2 mA and uses RD = 6 k-ohm. Find Rin, Avo and Ro. Also, if a load resistance of 10k-ohm is connected to the output
Draw a constellation pattern for a modern that uses eight equally-spaced phase angles and equally spaced amplitude levels. If the modern operates at 4800 baud, what is its bit rate.
What is the characteristic impedance of a coaxial cable that has an inner conductor diameter 0.108 in, an outer conductor diameter of 0.350 in, and a relative dielectric constant of 2?
The composite beam shown is made by welding C200 X 17.1 rolled-steel channels to the flanges of a W250 3 80 wide-flange rolled-steel shape. Knowing that the beam is subjected to a vertical shear of 200 kN
The terminals of an electrical device are labeled a and b. If vab = 10V , how much energy is exchanged when a charge of 3 C moves through the device from a to b. Is the energy delivered to the device (i.e., device dissipating or storing energy).
It was pointed out in the discussion that the digital filter will have linear phase.- Show this by determining and plotting the phase response of the filter for order=1 and order=30.
A 12 Ω resistor is connected in parallel with a 15 Ω resistor and the combination is connected in series with a 9 Ω resistor. If this circuit is supplied at 12 V
