Given a 1-phase 50 kVA 12.47 kV pf = 0.8 lagging static loada. 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.c. Suppose the load model of (a) is used in a 12.47 kV circuit. What is the value of S and I if the system voltage rises 5% (to 13.09 kV)?d. Suppose the load model of (b) is used in a 12.47 kV circuit. What is the value of S and I if the system voltage rises 5% (to 13.09 kV)?
What is bit rate of the transmission on the twisted pair? If the digital outputs of three identical video cameras are combined onto a single cable using time division multiplexing, what is the bit rate on the cable?
An ideal reheat Rankine cycle operates between the pressure limits of 10 kPa and 8 MPa, with reheat occurring at 4 MPa. The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
Telephone signals are typically sampled at 8000 Hz. a. What is the time interval between samples b. What is the highest frequency that can be recovered from a sampled signal
What is the minimum number of pins required for a socalled dual-op-amp IC package, one containing two op amps What is the number of pins required for a so-called quad-opamppackage, one containing four op amps
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
Write an assembly language program that initialize data X to 0, and then when input device inputs data it is added to X and when output device asks for data the value of X is output. a) Use Programmed I/O Mode of data transfer for inputting and out..
The steering wheel has backlash. This means there is a delay between the time the wheel is turned, and the time the car responds. The driver tends to overturn, which leads to instability and lack of control of the car.
You are working with a design team on a new product and are assigned to design the power supply. The requirements for the power supply are as follows: Input AC: 115 V AC +- 10%, 50-60 Hz Outputs: +5 V DC at 100 ma, +-12 V DC at 50 ma
For a face centered cubic, the volume of a conventional unit cell is a^3 Find the volume of a fcc primitive unit cell with three basis vectors: (0,0,0 --> a/2,0,a/2) and (0,0,0 --> a/2,a/2,0), and (0,0,0 --> 0,a/2,a/2)
The circuit arrangements for each of the installations, the final circuit cable selection, the maximum demand estimation, and the circuit protection arrangements should be designed.
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
