Hint: In contrast to direct current (DC), which travels exclusively in one direction, alternating current (AC) is an electric current that occasionally switches direction and varies its amplitude constantly over time. Alternating current is the type of electricity that is provided to companies and homes, and it is the type of electricity that is used by consumers when they plug in kitchen appliances, televisions, fans, and electric lamps to a wall outlet.
Complete answer:
A generator is a device that transforms motive force (mechanical energy) into electrical power for use in an external circuit in the production of electricity. Steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines, and even hand cranks are examples of mechanical energy sources.
The Faraday disc, the first electromagnetic generator, was created by British physicist Michael Faraday in 1831. Generators supply virtually all of the electricity used by electric power networks. An electric motor converts electrical energy into mechanical energy in the opposite direction, hence motors and generators are quite similar.
Dynamos and alternators are the two main types of electromagnetic generators. A commutator is used in dynamos to produce pulsating direct current. Alternators are devices that produce alternating current. A generator is made up of two parts: a spinning portion and a stationary part:The revolving component of an electrical machine is called a rotor.
The fixed portion of an electrical machine that surrounds the rotor is known as the stator. Michael Faraday developed the operating mechanism of electromagnetic generators in the years 1831–1832. An electromotive force is created in an electrical conductor that encircles a changing magnetic flux, according to the concept, subsequently known as Faraday's law.
Hence option B is correct.
Note: A transformer is an electrical device that uses electromagnetic induction to transmit energy between two or more circuits. A generator is a device that transforms mechanical energy into electrical energy for use in a circuit outside of the generator. A turbine is a rotating mechanical device that transforms energy from a fluid flow into usable work. An electric motor is a mechanism that transforms electrical energy into mechanical energy.
