A generator is an essential device in electrical engineering. Its primary function is to convert one form of energy into another.
Core Function: The fundamental purpose of a generator is to transform mechanical energy into electrical energy. This conversion is typically achieved through the principle of electromagnetic induction.
This process is the basis for most large-scale electricity production worldwide.
Therefore, the correct conversion is mechanical energy to electrical energy.
