Electric generators convert mechanical energy into electrical energy. This device must be mechanically linked to a driving machine (or primary machine), which has the ability to produce mechanical energy to move the generator's moving part. Generators are fundamental elements of the electric energy production system and are equipment that converts other forms of energy into electrical energy. Regarding the above, classify V for true sentences and F for false ones:

( ) Commercial electric generators of any size usually generate single-phase alternating current for distribution networks.
( ) The main characteristic of a generator is to convert mechanical energy into electrical energy.
( ) In Brazil, most of the consumed electrical energy is produced by hydrogenerators.
( ) The frequency of the electrical system is defined by the generator.

Choose the CORRECT sequence:


a) V - F - F - F.
b) F - V - V - V.
c) F - V - F - V.
d) V - F - V - F.
