Generator is a machine which converts mechanical energy into electrical energy.
For conversion of mechanical energy in to electrical energy, it uses electromagnetic induction principle.
For electromagnetic induction to happen, three things are required.
These are:
- Magnetic field
- Conductor
- Motion
So, when the conductor starts rotating through the magnetic field or the magnetic field cuts the conductor, emf( electromotive force) or voltage is induced in the conductor.
So, the conductor in which the voltage is induced in it is known as armature

A 100KVA DC GENERATOR HAS ARMATURE RESISTANCE 0.02 OHMS AND A SERIES FIELD RESISTANCE 0.004 OHMS WHAT IS THE ARMATURE GENETATED VOLTAGE?
There is not enough information to answer the question. A DC generator is never described in kVA because DC generators are specified in terms of kilowatts.
What is excitation of DC machine?
In general terms, 'excitation' simply describes the process by which an electric current produces a magnetic field. But, more specifically, it refers to the creation of the magnetic field by the field windings of a motor or generator. In the case of an alternator, for example, the armature windings (the windings into which voltages are induced) are stationary, and inserted into slots cut into the inner face of the stator. The field is then provided by the rotor which is supplied (via slip rings) with a 'excitation' current provided by an external d.c. voltage.
What is the formula for power in terms of amperes?
Electrical power = current x voltage Current is in amps
Why does AC load differ from DC load?
The terms a.c. and d.c. stand for alternating current and direct current, respectively.
What is the difference between a DC motor and a generator in terms of EMF?
During the operation of a DC motor, EMF is created across its terminals using an external source. Whereas, in a DC generator EMF is created across its terminal based on principle of dynamically induced EMF. So talking in terms of EMF, in DC motor EMF is consumed by the motor coil and utilized to rotate the axle. On the other hand, in DC generator EMF developed across coil is transfered to a load or a battery and consumed by them.
What is shunt current and a armature current?
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.

What is the difference between a field winding and an armature winding in any machine?
simply saying u that field winding is a winding present at the stator of the motor and is used to produce the magnetic field and the armature winding is the winding present in the rotor and is used to rotate the shaft of the motor. there are some machines with permanent magnets, those permanent magnets are used as the major source of magnetic flux in the machine instead of the field winding .
What are the parts of an generator?
There is no such thing as an AC generator, if it's DC it's a generator, if it's AC, it's an alternator.CommentThe above answer isn't correct, as 'generator' is a generic term applied to both d.c. and a.c. machines. It is perfectly correct to use the terms 'd.c. generator' or 'a.c. generator'. It is also correct to call an a.c. generator an 'alternator'.To answer the question, an a.c. generator can be broken down into two main parts: the 'stator' (stationary part) and the 'rotor' (rotating part). The field winding is part of the rotor assembly, and the armature windings (the windings into which the generated voltages are induced) are part of the stator assembly.
What is coil span factor and distribution factor?
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
What is an electric generator also known as?
Electricity generators were often traditionally called magnetos (especially on automoblies and tractors) and are also called alternators. Generally speaking, alternators and magnetos produce AC (alternating current), while generators produce DC (direct current), thought the terms are often used without regard to the type of current produced.
What are the three main components of a generator?
Drive shaft,Strong magnet,Coil of wire

What is the purpose of a generator in terms of energy?
It uses magnetic field to turn motion into electricity
Can you get banned from xbox live HALO REACH using a code generator?
Of course! Using any kind of generator can result in you breaking the terms of use, which will result in banning.
What is the primary purpose of a generator in terms of energy?
It uses magnetic field to turn motion into electricity
