Definitions:

High Resistance

A condition or property of an electrical component or circuit that opposes the flow of current, resulting in less current flow.

Voltage Drop

The reduction in voltage as electric current flows through a conductor, due to the impedance or resistance of the material.

Series Circuit

An electrical circuit in which components are connected end-to-end, so the current flows through each component sequentially.

Electrically Neutral

A state where an object or system has no net electrical charge and is not influenced by external electric fields.
