• Resumen

  • Unlike many other topics in basic physics, series and parallel resistances are rarely noticed in the real life of an ordinary individual, making it difficult to design a laboratory activity that can simulate something familiar. The activities described here entail minimal costs and are based on a puzzlelike game of tracking wire connections. A simple resistorbased device is built by students, which enables them to use a common multimeter to track down wire connections in a set of unmarked wires. A similar approach is sometimes used by electricians to identify wire connections.1
