Definitions:

Electrostatic Charges

Voltage developed by an excess or lack of electrons on an object.

Conductors

Materials that allow the flow of electrical current with minimal resistance, such as metals, due to their ability to freely move electrons.

Insulators

Materials that resist electrical current, used to protect, separate, or support conductors in an electrical system.

Static Charges

Electric charges that accumulate on an object's surface without an immediate opportunity to equalize through a circuit or ground.
