Three single-phase transformers are connected in a wye/delta configuration. Each single-phase transformer has an identical number of turns in the primary and secondary windings.If a line-to-line voltage of 480V is applied on the wye windings, compute the line-line voltage on the delta windings.
If the amplitude of the incident wave voltage at theload is 100V, determine the amplitude of the total voltage at theload, the distance from the load to the first voltage minimum and the amplitude of the voltage at this minimum.
Using MATLAB, plot the pole zero map and the Bode plot of the two transfer functions and paste the graphs below. Identify and briefly discuss the differences between the Bode plot of the two transfer functions.
A 10kW, 230V, 50 Hz, three-phase induction motor has full-loadefficiency of 86%, and power factor of 88%. It is supplied by a three-core cable 100mlong, having conductors of cross sectional area 16 mm^2 andresistivity 17.2nΩ m.
1. A 240 dc motor takes an armature current of 20A when running at 960 r/min. The armature resistance is 0.2ohm. Determine the no load speed, assuming negligible losses. 2. A 220 dc shunt motor has a srmature resistance of 0.3ohm.
We represent this by a non-overlapping sequence detector. In other words, asa soon as you detect the sequence, you will need to get another complete sequence to unlock. Therefore, you need to carefully choose to which state you will need to go.
A charge q is located at each corner of an equilateral triangle of side a. Find the magnitude of the force on each charge. Sketch the directions of forces.
Prove that the terminals of a voltage controlled current source (VCCS) can be connected so as to form a 2 terminal element that behaves exactly like a resistor.
What fixed point unsigned representation, with how many bits and how many bits to the left of the binary point, should we use if we need to represent numbers in the range 0 - 100 with a resolution of .001 or better
design a combinational circuit that, when given a 3-bit binary number as an input, will produce a binary number equal to the square of the input number as an output. Find the simplest expression for the outputs using K-maps.
In a line of sight link , the transmitted power = 1 watt at the frequency of 11 GHz and the transmitting antenna has gain of 1000 , the receiving antenna is 40 Km apart from the transmitting station
A current density J¯ = ˆy sin(2x) A/m^2 is subject to a z-directed magnetic field H¯ = ˆz10 A/m. a. Assuming the vacuum permeability (i.e. a non-magnetic medium), what is the magnetic flux
Develop the VHDL text file for a binary down-counter to divide a frequency by 32. Use Q as the outputs and CLK as the falling edge clock input.
