which device converts kinetic energy into electrical energy?\no an electric generator\no an electric…

Answer:

A. an electric generator

Brief Explanations:

An electric generator uses electromagnetic - induction to convert kinetic energy (from sources like turbines) into electrical energy. An electric motor converts electrical energy into mechanical energy. Transformers (step - down and step - up) are used to change the voltage levels of alternating current and do not convert kinetic energy to electrical energy.
