Definitions:

Electrical Resistance

The measure of the difficulty electrons face in flowing through a conductor, resulting in heat generation and energy dissipation.

Sectional Area

Sectional area refers to the area of a particular cross-section of a material or structural element, significant in physics and engineering for calculating stress, resistance, and other material properties.

Electrical Current Flow

The movement of electrically charged particles through a conductor or space, typically measured in amperes (A).

Conventional Theory

Asserts that current flows from positive to negative. Most automotive wiring schematics, terminology, and troubleshooting procedures are based on conventional theory. Its opposite is electron theory.
