 Outside of the town of Lakeview work is being completed on the Artemis 13 spacecraft. Another engineering and science task force titled T.R.O.J.A.N force are working with The Jet Propulsion Laboratory (JPL) Division of NASA testing a new and highly experimental spacecraft capable of in atmosphere flight as well as outer orbit maneuvering (Artemis 13). Lieutenant Pete "Maverick" Mitchell has been testing the new spacecraft now for a few weeks, including a detailed look at all the wiring in the spacecraft. His crew has been creating a model of the wire using multiple rings of charge, but they are having a difficult time justifying where the __constant__ electric field in the wire comes from. Initially, the crew created a model of the wire consisting of multiple rings, all with the same charge. But, the field doesn't look quite right - it's not constant as expected. It's up to you to adjust the code so that it models a constant electric field. Outside of the town of Lakeview work is being completed on the Artemis 13 spacecraft.

 +Maverick has been sufficiently convinced that the warning light cannot possibly take too long. Good job! In the meantime, his inspection of the wires has revealed a slight inconsistency in the circuit. It appears that half of the wiring is made from a 12-gauge copper wire and half is made from an 18-gauge copper wire. Maverick is worried about the affect this will have on the circuit. He has asked your team to report the effects of the different sized wires on the electric field, the surface charges, and the current in the wires.
