Experiment description
This experiment demonstrates how different materials conduct electricity. A simple circuit with a battery and bulb is used, and the test material is placed between two wire ends. If the bulb glows, the material is a good conductor. If it does not glow, the material is a poor conductor. Metals allow the bulb to glow brightly, graphite allows it to glow dimly, and materials like plastic, wood, and rubber do not allow current to pass.
