states that charge can be transferred from one object to another but cannot be created or destroyed | law of conservation of charge |
material, such as copper wire, in which electrons can move easily | conductor |
material in which heat flows slowly | insulator |
process of transferring charge between objects by touching or rubbing | charging by contact |
process of rearranging electrons on a neutral object by bringing a charged object close to it | charging by induction |
the net movement of electric charges in a single direction, measured in amperes | electric current |
related to the force that causes electric charges to flow; measured in volts | voltage difference |
