Question

You are stranded on a deserted island with 100m of 18 gauge insulated copper wire, a light bulb rated at 3.0V, a 50V battery, a large iron nail, a few simple tools (including wire cutters), and your clothes. There are of course trees, rocks, sand, and other assorted island flora and fauna. (The island is a bit unique: there is a dampening field present that inhibits fire.) Since you have been stranded on the island, each night after dark a helicopter flies over. Using the materials at hand, describe a way to get yourself rescued. (You must support your description by including brief references to any laws or equations that apply, and draw a diagram)
