Generators and alternators are the primary methods of producing electric power.

Generators are useful appliances that supply electrical power during a power outage and prevent discontinuity of daily activities or disruption of business operations. Generators are available in different electrical and physical configurations for use in different applications. In the following sections, we will look at how a generator functions, the main components of a generator, and how a generator operates as a secondary source of electrical power in residential and industrial applications. An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

The battery provides electricity needed for the starter motor to start the car. When the car is running, the alternator generates energy to feed the electrical system and charge the battery. The alternator used to be called a generator, and it works in a similar way.

When most people talk about a generator, their mind roams towards a portable generator you would use as a home backup or for a recreational vehicle. Then, when we think about an alternator, we think of the device used to provide power to our car battery. First, what is an alternator?

Difference Between Alternator and Generator

You may think your battery is powering all things electrical in your car, be it your windshield wipers, headlights or radio. The alternator is a generator whose purpose is to distribute electricity to the car and recharge the battery. About the size of a coconut, the alternator is generally mounted to the front of the engine and has a belt running around it. The components of an alternator are geared toward providing the right type and right amount of power to the vehicle. The rotor and stator are the electricity-producing components of an alternator. The movement of the magnets over the wiring is what ultimately creates electricity.

The major difference between the alternator and the generator is that in alternator the armature is stationary and the field system rotates whereas in the generator armature rotates and field is stationary. The armature of the alternator is mounted on the stationary element called stator and field winding on a rotating element. While the connection of a generator is just the reverse of it. The other differences between them are shown below in the comparison chart. The alternator and generator both works on the principle of Faraday law of electromagnetic induction. The generator induces both the alternating and direct current and the alternator produces only alternating current.

You have to go to the bank, Finn. Rest assured, that shall certainly happen, whether anyone likes it or not. Such tanks, previously held back for fear of reminding Afghans of their Russian occupiers, were, according to an unnamed U. None of this had anything to do with winning hearts and minds, just obliterating them. I thank him and return to the hospital.

The alternator induces the AC, whereas the generator causes both the AC and DC power. The generator produces the alternating current which is converted into DC by the help of the commutator. The alternator takes input supply from the stator whereas the generator takes input supply from the rotor.

What Is The Difference Between An Alternator And A Generator?

Basically, an AC generator is an electrical machine that converts mechanical energy into electrical energy in the form of Alternating Current AC. Basic principle behind the working of an AC synchronous generator is also Faraday's law of electrical induction , somewhat similar to working of a DC generator. If a closed path is provided to the conductor, induced emf causes current to flow in the circuit. Now, in the above figure, let the conductor coil A-B-C-D is placed in a magnetic field. Direction of the magnetic flux will be from N pole to S pole.
