What is the primary function of a generator in the electrical grid?

The primary function of a generator in the electrical grid is to convert mechanical energy into electrical energy. Generators achieve this by using mechanical input—often from turbines that are driven by steam, water, or wind—to rotate a rotor within a magnetic field. This movement induces an electrical current according to Faraday's Law of electromagnetic induction. The generated electricity is then transmitted through the power grid to supply homes, businesses, and industries.

This conversion process is fundamental to the electrical grid, as it establishes the generation of electricity needed to meet the demands of consumers. Generators are pivotal in various roles, from large-scale power plants that produce electricity for widespread distribution to smaller generators that may serve specific applications. Understanding this primary function is crucial for grasping the overall operation of electrical systems and the integration of power sources within the grid.
