Answer:
C) electrical energy
Step-by-step explanation:
A generator is based on the principle that when a conducting coil rotates between poles of magnet, an emf is induced in the coil and current is produced. By this way, a generator converts mechanical energy to electrical energy. It is based on Fleming's Right hand rule.
A generator consists of a rotating wire coil placed in a magnetic field. This process transforms mechanical energy into electrical energy.
