Electric Current Solves Mazes
Ayrinhac, Simon
Physics Education, v49 n4 p443-446 Jul 2014
We present in this work a demonstration of the maze-solving problem with electricity. Electric current flowing in a maze as a printed circuit produces Joule heating and the right way is instantaneously revealed with infrared thermal imaging. The basic properties of electric current can be discussed in this context, with this challenging question: how can the electric current choose the right way and avoid dead ends?
