How can you learn whether or not a material can conduct electricity?

Answer 1

You need a battery, a light bulb, and three pieces of copper wire, as well as the thing you want to test. Create a circuit by connecting each object to two others with the copper wire. Place one end of a copper wire on the positive side of the battery, the other end on the bottom of the light bulb. With the second wire, connect one end to the side of the metal part of the light bulb (where you see the ridges), and the other end to the object. With the last wire, connect one end to the object and the other end to the negative side of the light bulb. If the light bulb lights up, then the object is conducting electricity. If you have a large light bulb, it won't show as much light, or maybe no light at all, even if you have a conductive material. It is better to use a smaller light bulb for smaller batteries, so you can see the light.

Answer 2

You can learn whether a material can conduct electricity by testing its conductivity using a simple circuit with a power source and a light bulb or multimeter. If the material allows electricity to flow through it and the bulb lights up or the multimeter registers a reading, then the material can conduct electricity. Materials that have free electrons that can move easily, like metals, are typically good conductors of electricity.
