Learning Statements:

· Excelsior College really set me up for success from day one of different science and math course I took while working on obtaining my degree. Through these different courses I was either guided to get perform electronics related examples or the examples were just part of the curriculum. While taking the Physics I and Physics II we were directed to figure out many electrical related problems or problems that related to our course of study. One particular problem I remember from Physics II dealt with copper wire and how long it could be if the resistance was a certain percentage of load resistance. The formula we used for this was , where R is resistance, p is resistivity which was given in a table for the example material, L is the length of the wire and A is the Area of a cross section of the wire. Resistivity is given in Ohm Meters (Ωm) and varied between very low resistivity like copper at 1.69E-8 Ωm to very high resistivity like rubber at 1013 Ωm. L is the length of the conductor in meters. A is the area of the cross section using πr2, where r is the radius. A Physics homework assignment is provided as evidence of my understanding of natural phenomena. (Tab C-1, Physics homework, p. 7.40)

· In Calculus (Tech 201), I had many problems involving electrical systems; one particular problem was one that had us find how many Columbus pass a point in a circuit after a given amount of time. This was one of my first integration problems and it really opened my eyes as to the potential of Calculus in electronics and electrical systems. While this was a fairly simple calculus problem it shows my understanding of science and math in electrical engineering technologies. Using the formula: , I was able to find that after 1.6 mS, when the current in a chip is .330uA that .528 nC pass a single point in the circuit.

· In Control System ELEC 321, we used a lot of Differential Equations, specifically Laplace Transforms to find an overall control formula for a closed loop system. These differential equations were quite difficult to grasp at first, but after going over many examples and problems, and utilizing them to find transfer functions of a system it was easy to see how these math tools were useful for these types of problems and specifically for controls system engineers. In module 2 of my control systems class we were given a transfer function and asked to find y(t) when r(t) was a unit step input. With T(s) given as and we know that a step input is R(s) = 1/s. With this information it is possible to find y(t) as 1 – 2e-4t + e-8t.
