2. Course Description At RPI, we offer two related degrees built on the basic phenomena of Electricity/Electronics, Computation and Information: Electrical Engineering & Computer and Systems Engineering. To prepare first year students for successful undergraduate programs in these two degrees, this course provides an introduction to engineering analysis and engineering thinking in four general areas:

3. Course Description Basic Circuits and Electronics (experimentation, simulation, circuits and electronics fundamentals, tinkering); Programming (Matlab, Embedded Systems); Mathematics (Linear Algebra and the Mathematics of Computation); Engineering Systems (Electrical, Electro-Mechanical, Electro-Optical …).

4. Course Description The overall goal of this course is to help students build a broad analysis skill set so that through experimentation, simulation and the application of science, mathematics and engineering fundamentals, they can develop useful systems models that enable engineered solutions addressing a broad array of societal needs.

8. NY Regents Electricity • A Coulomb is charge, an Amp is current [Coulomb/sec] and a Volt is potential difference [Joule/Coulomb]. • Short fat cold wires make the best conductors. • Electrons and protons have equal amounts of charge (1.6 x 10-19Coulombs each). • Adding a resistor in parallel decreases the total resistance of a circuit. • Adding a resistor in series increases the total resistance of a circuit.

9. NY Regents Electricity • All resistors in series have equal current (I). • All resistors in parallel have equal voltage (V). • If two charged spheres touch each other add the charges and divide by two to find the final charge on each sphere. • Insulators contain no free electrons. • All charge changes result from the movement of electrons not protons (an object becomes positive by losing electrons)

10. NY Regents Electricity • Ionized gases conduct electric current using positive ions, negative ions and electrons. • Electric fields all point in the direction of the force on a positive test charge. • Electric fields between two parallel plates are uniform in strength except at the edges. • Millikan determined the charge on a single electron using his famous oil-drop experiment.

11. Background Survey • Select a Partner but Do Survey Individually • Survey Monkey • Personal Information (complete fully) • Technical Background (guess if you do not know) • Go to survey • Work on It Now for 15-30 Minutes • Time is not fixed. • Will wait until about half of class is finished
