| Continuing T.R.O.J.A.N forces collaboration with the Jet Propulsion Laboratory (JPL) Division of NASA, you and your team are working with a group of electrical engineers at Lightbulbs'R'Us. Given the problems that Lieutenant Pete "Maverick" Mitchell has been having with the warning lights, the Jet Propulsion Laboratory (JPL) Division of NASA has placed a large order for a new set of warning lights for their power delivery system. They have told you that a current of 2.5 A down the carrier wire should turn on the warning light. Unfortunately, due to JPL's time schedule, you do not have time to order LED bulbs and must construct the lightbulbs the old fashion way using a filament (very thin piece of wire, diameter = 0.1 mm) connected to the carrier wire (normal electrical wire, diameter = 1.63 mm). You happen to have the following [[184_notes:metals|metals in the warehouse]], with known electron densities and electron mobilities. Which metals do you want to use for the carrier wire and for the filament? JPL would also be interested in knowing what kind of battery would be needed to power the lightbulbs and the electric field from the surface charges on your wires to make sure it doesn't interfere with their other equipment. | Continuing T.R.O.J.A.N forces collaboration with the Jet Propulsion Laboratory (JPL) Division of NASA, you and your team are working with a group of electrical engineers at Lightbulbs'R'Us.

| The Artemis 13 has launched and T.R.O.J.A.N force is on board and currently hanging in lower Earth orbit. You and a team of scientists are testing the life support systems for extended space travel aboard the ship. During a training exercise, your android co-pilot Johnny 5 begins to malfunction, it is essential that Johnny 5 not lose all power as he has an important role in the mission. Andrea Baker, the team leader mentioned that in a [[https://www.youtube.com/watch?v=H-vXydxLZMk|training video]] she saw back in the 80's call "Short Circuit 2" a model like Johnny 5 was brought back to life using a defibrillator. | The Artemis 13 has launched and T.R.O.J.A.N force is on board and currently hanging in lower Earth orbit.
