# Review question

EEE241 Midterm Diaz Rules: This is a take home midterm. That means you cannot discuss the test with anyone and you certify that the work you turn in is only your work. When you are done please email me a pdf scan of the work. Make sure any figures you and any equations you write are legible. Make sure if you make any assumptions or assign any values to a variable that you clearly state so. You must make it clear what you are doing and why you use the equations you use by clearly labeling the terms. Tell me what I need to know to understand you approach in concise terms.

EEE241 Midterm Diaz Rules: This is a take home midterm. That means you cannot discuss the test with anyone and you certify that the work you turn in is only your work. When you are done please email me a pdf scan of the work. Make sure any figures you and any equations you write are legible. Make sure if you make any assumptions or assign any values to a variable that you clearly state so. You must make it clear what you are doing and why you use the equations you use by clearly labeling the terms. Tell me what I need to know to understand you approach in concise terms. A midterm that consists of a series of scribbled equations that are too small to discern and a final answer with no explanation is not acceptable. You are free to use the text, the notes, calculators, MathCAD. You can use any results given in the text or notes by simply stating it. You do not need to rederive equations already derived in class. Just tell me how you will use them and use them. Choose either Midterm A, which looks like the homework or Midterm B which is a boundary value problem. Please email me when you decide which one you are doing. Remember, you have three hours form the time you accessed the test and downloaded it.
Midterm A: (Two problems A1 and A2) A1) Estimate (calculate approximately) the capacitance of a two wire line brought close to ground as shown in the Figure. Follow the approach discussed in the notes where you assume one conductor has +? C/m and the other â??C/m and therefore you know the voltage difference between the conductors (that is ?V from f to g) when the line was in free space. Then you draw the images of the charges and calculate the excess ?V created between points f and g so that you can calculate the new ?V total. Then C=???Vtotal. (Hint: Draw the images and clearly label their location and every distance you care about).
A2) In the Figure there is a partially filled 3D Capacitor with three different regions. The plates are 1m x 1m and the plate…
