Generators

A generator is a device that converts mechanical energy into electrical energy. It operates on the principle of electromagnetic induction, discovered by Michael Faraday in 1831. Generators are essential in producing electricity for various applications, including powering homes, businesses, and industries.

How Generators Work

Generators consist of a rotor (the moving part) and a stator (the stationary part). When the rotor is turned, it induces a flow of electrons in the wire coils of the stator, creating an electric current. This current is then transferred through wires to power electrical devices.

Types of Generators

• Portable Generators: These are small, versatile generators used for temporary power supply during emergencies or outdoor activities.
• Standby Generators: These generators are permanently installed and automatically provide power during outages. They are commonly used in homes, hospitals, and data centers.
• Industrial Generators: Designed for heavy-duty use, these generators are used in large-scale operations such as construction sites, mining, and manufacturing plants.
