What is the primary function of a generator?

The primary function of a generator is to convert mechanical energy into electrical energy. Generators operate on the principle of electromagnetic induction, where mechanical energy, often provided by a rotating engine or turbine, interacts with magnetic fields to produce electric current. This process is fundamental in various applications, ranging from small portable generators to large power plants, enabling the conversion of kinetic energy from motion into useful electrical power.

While the other options may involve processes related to energy, they do not accurately define the core purpose of a generator. For example, devices that convert electrical energy into mechanical energy are typically known as motors, which serve a different function. Generating heat from electricity is a property utilized in resistive heating devices, not generators. Lastly, storing electrical energy is the function of batteries or capacitors, which is distinct from what generators do. Understanding the primary role of generators is essential for comprehending how electricity is produced in various settings.
