Conclusion #2 - Part B Janet K Lee A09590840 Physics 1BL In this lab, we studied what conditions allow for charges to move around an electric circuit. To experiment what kinds of materials are required to form a functional circuit, we connected several different objects to the circuit to see whether the light bulb lights or not. It does matter what kind of materials you use to connect the battery to the bulb. Only conductors will complete the circuit and allow the light bulb to light. Insulators such as glass, plastic, or rubber, the light bulb will not light because they do not complete the circuit. When the iron nail is placed in the circuit, the bulb lights up because it is a metal, which is a conductor. We removed the nail from the circuit and replaced with a glass rod, and the bulb did not light because the glass rod is an insulator. Then we tried the same experiment with the metal part of scissors, and the bulb did light. When we used a wooden stick, the bulb didn’t light up because wooden stick is an insulator. The bare
