Conductors
Conducting material allows electric current to travel with little resistance throughout. This is related to the structure of the atoms of the conductor. In this section, we will look at what a conductor is, why it is this way, and the applications.
The Main Idea
Conductors are defined a material that allows charged particles to move easily throughout. Charges placed on the surface of a conductor will not simply sit there or only spread over the surface, it will immediately spread evenly throughout the conductor given there are no interfering forces. If the conductor is in an electric field, for example, it will cause the (negative) charges to move in the opposite direction of the field.
how conductors work atomically Electric current flows by the net movement of electric charge. This can be by electrons, ions, or other charged particles.
Conductors allow for easy movement of charged particles because of the structure of the atoms. The outermost electrons in the conductors are only loosely bound and allow for more interaction with other particles. The idea that electrons move completely free from their atom in the conductor is not entirely accurate, but it will be a perfectly working approximation for our level of analysis.
