Definitions:

Ohm's Law

A fundamental principle of electricity stating that the current through a conductor between two points is directly proportional to the voltage across the two points.

Dielectric

Something that limits or blocks current flow. Nonconducting dielectric material is used between poles in a capacitor and dielectric grease can be used to protect exposed terminals.

Conductors

Materials that allow the flow of electrical current, commonly used in electrical wiring and electronics for the transmission of electricity.

Voltage Drop

A decrease in electrical potential along the path of a current through a circuit.
