Abstract

This chapter presents a physical method to solve a maze using an electric circuit. The temperature increase due to Joule heating is observed with a thermal camera and the correct path is instantaneously enlightened. Various mazes are simulated with Kirchhoff's circuit laws. Finally, the physical mechanisms explaining how the electric current chooses the correct path are discussed.
