300 ? 5:1 100 V rms CV2 m 8? 1. Find the average power delivered to the 8 Ohm load in the circuit above if c equals: a. 0 b. 0.04 S c. -0.04 S 2. Use Matlab to write a script that plots a graph of the power and coefficient relationship as follows: a. Power on the y axis b. c on the x axis c. c has a range off 0 to 0.08 S d. you must have a minimum of 100 data points in your graph e. label your graph f. explain based on your graph how the dependent current source affects the power delivered to the load 3. Use Matlab to plot v2(t) and i2(t) on the same graph, for c = 0 and: 1. f = your last 4 digits of your 95# 2. plot 2 periods 3. explain based on the figure the power factor of the resistor

Problem 3 (20 points): A uniform sphere of mass 20 kg and radius 5 m is projected along a rough horizontal surface with a linear velocity V = 10 m/s towards the right and no angular velocity. The coefficient of kinetic friction between the sphere and the surface = 0.3. Determine (a) the time t1 at which the sphere will start rolling without sliding, (b) the linear and angular velocities of the sphere at time t2.

Assignment 2.1 Binary 8-bit up or down switch controlled counter: The objective of this practical assignment is to familiarize the learner with the PIC microcontroller's decision making ability and how to debouncing an input switch contact. Pushbutton switches connected to input configured port pins will be used to control the program counting sequence. 1. Write a program to demonstrate an 8-bit binary up or down counter displayed on the LED's connected to PortD(0-7). 2. When the pushbutton connected to port pin RA4 is held in the pressed position, the LED displayed 8-bit binary value must count up continually every 1½ second. 3. When the pushbutton connected to port pin RAO is held in the pressed position, the LED displayed 8-bit binary value must count down continually every 1½ second. 4. Counting must stop only when both the input pushbutton switches are released. 5. First use a flowchart to determine the program structure and then generate your commented firmware source code. NB: When switches are used on Port A then the port must 1st be made a Digital port(p166). When test for switches pressed use BTFSS or BTFSC instructions.
