Definitions:

Electrical Resistance

A measure of the opposition to the flow of electric current through a conductor, resulting in electrical energy being converted into heat.

Ohms

The unit of electrical resistance, representing the resistance between two points of a conductor when a voltage of one volt produces a current of one ampere.

Circuit Protection

Devices such as fuses, fuse links, and circuit breakers in an electrical circuit that stop the flow of electricity in the event that a fault occurs in the circuit. These help to protect people from injury and prevent damage to the vehicle’s electrical system.

Fuse Links

Safety devices in electrical systems that melt and break the circuit when current exceeds a certain level, preventing overheating.
