In modern vehicles, electrical systems play a crucial role in powering a wide array of components, from the headlights and air conditioning to the engine and safety features. To ensure that these systems function properly and safely, components such as relays and fuses are integrated into the vehicle’s electrical circuits. Although they both serve to protect and control electrical flows, they have distinct roles and operate in different ways. In this article, we will explore the key differences between a relay and a fuse in a car, their functions, and why both are essential for maintaining the integrity of a vehicle’s electrical system.
