Sneakers (1992) is by far one of the best nerd movise ever made. The cast is all-star. The science, aside from the major premise of the movie (you have to be willing to suspend some disbelief to watch any hollywood movie; why not the overall premise? it wouldn't be any worse than what you have to do to yourself to watch Snakes on a Plane) is tight. The acting is top-notch. The plot is complicated enough to hold interest, but simple enough to be reasonable.
One night when his charge was pretty high, Micro-Farad decided to seek out a cute little coil to let him discharge. He picked up Milli-Amp and took her for a ride on his Megacycle. They rode across the Wheatstone bridge, around the sine waves, and stopped in the magnetic field by the flowing current. Micro-Farad, attracted by Milli-Amp's characteristic curves, soon had her fully charged and excited, her resistance to a minimum. He laid her on the ground potential, raised her frequency, and lowered her reluctance.
Her figure described a set of parabolas that could cause cardiac arrest in a yak.
