A designer searches for a simple circuit to provide one-third of a signal current I to a load resistance R. Suggest a solution using one resistor. What must its value be? What is the input resistance of the resulting current divider? For a particular value R, the designer discovers that the otherwise best resistor is 10% too high. Suggest two ciruit topologies using one additional resistor that will solve this problem. What is the value of the resistor required? What is the input resistance of the current divider in each case?
A 230V shunt motor having an armature resistance of 0.05 W and a field resistance of 75 W draws a line current of 7 A while running light at 1120 rev/min. The line current at a given load is 46 A.

Write a MATLAB script to implement the linear congruential algorithm to generate 5000 pseudo-random variates in the interval (0,1). Use the following parameters: seed=17; A=1103515245; M=2147483648; C=12345.
Write a program that reads a file containing only integer, but some of the integers have embedded commas, as in 145,020. The program should copy the information to a new file, removing any commas from the information.
The tuning control is required to provide a uniform, linear change in frequency for a fixed rotation of the knob, e.g., 25 kHz per revolution at any operating frequency. You are considering three options for controlling the frequency
draw the sympol and truth table of the gate that corresponds to the action of the logic gate.
Traffic lights are being converted from incandescent bulbs to LED arrays to save operating and maintenance costs. Typically each incandescent light uses three 100-W bulbs, one for each color R,Y,G,A competing LED array consists of 61 LEDs.
