+==== Project 15B: Those Pesky Grinch EM Boar Tigers ====
+{{  184_notes:grinchyboartigers.png?500  }}
+Instead of investing in a Christmas tree this holiday season, the physics department has decided to invest in a large hologram machine with the capability of displaying an image contained within the dimensions of 3m x 1.2m x 1.2m. Now all they need is a program to create an image to be displayed. Being physics nerds, they decide to tackle the task using one resource: charges. Who wouldn’t want to unwrap the 6x6 Rubik’s cubes, eat cookies, and share physics jokes around huge imaginary charges and their corresponding magnetic and electric fields?!
+You and your team have volunteered to take on the task of designing a circuit for the hologram to display the most festive Christmas tree, since you figured that all you’ve been doing this semester is dealing with those tiny little invisible bastard charges anyways. Despite your best arguments, the department has refused to fund the expensive hologram and has promised to buy you a normal Christmas tree. So instead, your task is to design a circuit for the most festive Christmas tree to spread joy and cheer. Your tree must be dressed in four strands of lights, two of which wrap around the tree trunk and two that wrap around the outside of the tree, and a star at the top of the tree. The strands of lights all should have half the brightness of the star. If the power goes out, the star should still be able to shine bright for a few more seconds on the tree.
+Unfortunately, those pesky Grinch EM boar tigers, especially Max, are at it again and are plotting to ruin your beautiful new Christmas tree! You will also need to find the B-field to ward off the Grinch boar tigers. For the full safety of your tree, you need to repel the Grinch tigers from 2m away. From the lovely grad students in the stock room, you know that: the power of one strand of lights is 40.8 W, the power of the star is also 40.8 W, the battery at the base of the tree has a voltage of 12V, and the capacitor in your circuit should be $5\cdot 10^{-6}$ F.
