Relay technology has become a cornerstone in various fields, ranging from electronics and computer science to sports and communication. While the term “Relay” might evoke different associations depending on the context, its significance is undeniable. In this article, we will delve into what Relay is, its applications, and how it plays a crucial role in modern advancements.

What is Relay? At its core, a Relay is a device used to control the flow of electrical current in a circuit. It acts as a switch, allowing a small current to control a larger one. Traditionally, relays have been a fundamental component in electrical engineering, where they enable automated control systems, protect circuits, and provide remote control capabilities. They work by using an electromagnet to operate a mechanical switch. When an electric current flows through the coil of the electromagnet, it creates a magnetic field that pulls a switch, thereby opening or closing the circuit.
