The field current is used to create an electromagnet. The power out of a generator comes from the prime mover (the thing that is making the rotor spin), not the field current. The field current is necessary to set up an electric field to induce electric current onto the stator windings. The stronger the electromagnet, the harder it is for the prime mover to spin (similar to a high gear on a bicycle), causing more power to be needed to keep the prime mover turning.

What is a shunt generator?
A shunt generator is a method of generating electricity in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.A direct current (DC) generator, not using a permanent magnet, requires a DC field current. The field may be separately excited by a source of DC, or may be connected to the armature of the generator so that the generator also provides the energy required for the field current.
How does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
Does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
Is the critical resistance of shunt field less or more than the field resistance of generator?
More due to the impedance levels in the generator
What does an electromagnet do in a generator?
in a generator electromagnets are used for producing flux for rotor to cut so it can produce current in small generator they will have residual magnetism and in big generator current is supplied to electromagnet from another small dc generator
How does a generator exciter work?
Exciter controls the magnetic field in the generator system and controls the output voltage and/or current.
How do you raise voltage in generator?
Increasing the field current will boost the generator output voltage, assuming the governor doesn't limit.
How is a generator and a electromagnet alike?
Both a generator and an electromagnet involve the use of coils of wire with an electric current flowing through them. In a generator, the motion of the coil creates an electric current, while in an electromagnet, the electric current produces a magnetic field.
What thing can we do to increase the size of the current the generator produces?
To increase the size of the current the generator produces, you can increase the strength of the magnetic field, increase the speed of rotation of the generator, or increase the number of turns in the generator coil. These factors all contribute to the overall output of the generator.
How is energy transferred by a generator?
Energy is transferred by a generator through electromagnetic induction. As the rotor inside the generator spins, it creates a changing magnetic field that induces a current in the wire loops of the stator. This current is the electrical energy that is then transferred out of the generator for use.
What are the parts of a direct current generator?
there are many parts of a dc generator armature, field coil, yoke, body, rotor and commutator.
How do you raise generator voltage?
A generator's terminal voltage can be raised by increasing the field current. This will result in an increased load on the generator, which will slow it down unless the governor kicks in to keep the generator at speed.
