This assignment is for students who have missed a class and need to make up their class participation grades. Students who have not missed any classes may complete this assignment for extra credit. A student may do this assignment only once.

Wire Gauges

Electric circuits typically are constructed from wires. Wires come in many sizes, or gauges. Make a wire gauge display board that shows many different wire gauges, both solid and stranded wire. You must have samples of well over a dozen different gauges, each one neatly labelled with what gauge it is, what is its maximum current, and what is its resistance per length. The samples must be mounted on a wooden or other rigid board. The gauge display board must be durable—in other words, when the professor drops it on the ground, it has to hold together without damage. A crude sample (too few gauges for credit) is shown here.

What to turn in (hardcopies only):

· A copy of your completed Part 1 and Part 2 forms for the day of class participation that you are making up

· Your gauge display board

Students who complete this project can replace a day of missed Participation Grades for both Part 1 & Part 2 grades.

Students who do this project for extra credit can replace the Part 1 & Part 2 grades of any day of their choosing with 100% A+ grades. They must tell me which day they want the extra credit applied toward. Note that this is not much extra credit.
