TOTAL 175 Your overall score on Midterm #2 will be the sum of your numerical scores on Problem #1 and Problem #2, plus your BEST TWO SCORES on any TWO of the remaining three challenge problems (Problems #3, #4, and #5), plus any points earned on the extra-credit problem (Problem #0). Electricity is often called wonderful, beautiful; but it is so only in common with the other forces of nature. The beauty of electricity or of any other force is not that the power is mysterious, and unexpected, touching every sense at unawares in turn, but that it is under law, and that the taught intellect can even govern it largely. — Michael Faraday, 1858 Some DO’s and DON’T’s: Do spread out in the room as much as possible. Do NOT turn the page and begin the exam until instructed to do so. Do feel free to use an electronic calculator (without wireless capabilities), and ONE double-sided 8 1 2 by 11 inch page of handwritten notes . Do NOT use any other notes, books, references, or electronic devices. Do feel free to keep a beverage and a QUIET snack available, if you need them. Do read through the entire exam before beginning any calculations or analysis. Do raise your hand or come quietly to an aisle or the front to ask a question. Do try to use the spaces provided for your answers, but do ask for extra paper if needed. Do remember to clearly label and staple any additional pages you wish graded to the back of your exam. Do ask for clarification if you are unsure about the wording or interpretation of any problem, or are uncertain of what is being asked. Do keep an eye on the board and an ear to the proctor(s) for any hints, corrections, or announcements. Do work to maximize credit – try to obtain at least partial credit on each part of every problem; work clearly and write legibly; show all work you wish to be evaluated, using the front and back sides of the exam paper; box or circle final answers wherever possible. Neatly cross out any work that you do not wish to be evaluated. Do explain your reasoning clearly, carefully, and concisely – if you do not show relevant work or reasoning for any part of a problem, you may not be awarded any credit, even if the final answer is correct. Do verify dimensions and units. Do pay attention to signs and significant figures, and do clearly state your sign conventions. Do NOT in general plug in numerical values too early in the calculation, or risk making mistakes that the graders cannot easily assess....
