Conductors Once you have charged a conductor, how do discharge it (when you are done with your experiment)? You use the fact that the Earth is a big reservoir for electrons (it can accept or give as many electrons as you want). You need to make a pathway from the conductor to the Earth for the electrons to freely move. This is called “grounding.”

Insulators Insulators are objects in which charges (electrons) cannot move freely through. Examples of insulators are glass, plastic, rubber and wood. If you put a charge on a small region of an insulator, the charge will remain in that region. There is no tendency for the charge to move into other regions of the material.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
