Three single phase transformers with a turns ratio of 1:1 are connected to form a three phase transformer. The transformer input is a three wire three phase 120V (line-to-line) system. the transformer output supplies a "Y" connected three phase load with a phase impedance of 600 + j300 ohms. A. sketch the diagram of the system described above. B . For each of the transformer configurations in the table below, find the phase voltage, and phase current at the load, and the input power (real power) supplied by the source.
An infinite grounded conducting tube of radius 10cm is centered on the z axis. A concentric charged tube of radius 6 cm has a surface charge density of 24 uC/m2. A 1m long section of the charged tube is compressed to change its radius to 3 cm.
A source X produces symbols A, B, C, D, and E with probabilities 0.5, 0.25, 0.125, 0.0625 and 0.0625 (a) Find the information content of X. (b) Give a fixed length code for X. Compute its efficiency. (c) Derive a Huffman code for X
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
If the efficiency of the motor and drive system is 80% and it is fed through a transistor regulator at 12V, what is the mean current through this regulator when the printer is working continuously?
Step-down transformer
At the output of a two terminal DC network, when no load is attached , the voltage measured as 6 volts. When a load of 1 kiloohms is connected across output, the voltage at the output drops to 4 volts. Create a Thevenin Equivalent model of this ne..
Look at the resistor illustrated. Based on your knowledge of the resistor color code, what are the resistance value and tolerance of this resistor?
Suppose that the source charges of the two previous problems are present together. The potential at infinity is defined to be 0. a. Is the potential at the point (0.5, 0.5, 0.5) positive, negative, or zero b. Is the potential at (4, 4, 4) positive
Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150(that is, $95 parts
What are the techniques used to make feedback system stable? Explain and draw the frequency response of a 1-pole feedback amplifier.
Students should type up, assemble and emulate the BIN2ASCII program which converts the value entered in R3 from Hexadecimal to ASCII. This should be done by dividing R3 by 10 (decimal) and converting the remainder to ASCII
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 10 , inductive reactance XL = 20 , and a capacitive reactance XC = 10 . All three components are connected in parallel to the source.
