Purpose:
Complex circuits are frequently useful circuits. By providing a specific voltage and
specific current at a specific location, the output of devices can be controlled: motors,
user interfaces, lights, etc. Using simple materials like batteries, wires, switches, and
bulbs, one can create electrical puzzles, challenging the viewer to infer the layout of the
circuit based on circuit output (e.g., relative brightness of bulbs).
Light puzzle:
We created the following light puzzle.
Make a circuit diagram of your light puzzle. Use
appropriate conventions.
Include a photograph of your completed puzzle
