Answer the following question given this paragraph: 

Generators may be set up to produce either direct or alternating current. Generators in cars and most power plants produce alternating current. Regardless of the type of current, all generators change kinetic energy to electrical energy.


Q: When using a generator, we are transforming what energy into what energy?

 Choices:

- magnetic into kinetic

- thermal into radioactive

- mechanical into thermal

- kinetic into electrical

A:
kinetic into electrical
