If you mean an alternator as used in cars, the main current-carrying winding is the stator, and the armature (rotating part) only carries the current needed to set up the magnetic field. In that way an alternator is inside-out compared with some other types of electrical machine.
The advantage of an alternator is that it uses slip-rings instead of a commutator and you have two slip rings connected by brushes to carry the relatively small current from the voltage regulator to the armature coil so that the alternator generates the right voltage at all speeds. This arrangement ensures a long brush life and high reliability.
The main coil (stator) produced 3-phase ac which is connected via a full-wave rectifier with six diodes directly to the battery. It is also connected to another rectifier that produces a secondary dc circuit that feeds the voltage regulator. When the engine is not running, current flows through the ignition light from the battery to the secondary dc circuit, so it glows when the ignition is switched on and goes off as soon as the engine runs up.

Does current flows through fruits?
If the voltage is great enough a current will flow.
Why can't electricity flow through coin?
It can.Electricity, both static and current, flows through coins quite easily.
What is an electric current flow diagram?
This good? the current flows through the battery and light?
What is it called when too much current flows through a conductor?
It is called a short circuit when more current flows than what the load demands.
What is the continuous loop that an electric current flows through?
DC = direct current.
What flows through a complete circuit?
Current flows through a complete circuit.
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
How does a current flow through a wire?
according to kcl the current flows through a wire
True or false The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit?
True
What is the current that flows through an unloaded voltage divider?
The Bleeder current.
What is a large stream of moving water that flows through the ocean?
The stream of water which flows like a river through the ocean is a current. The Gulf Stream is the most significant such current which flows from the tropics to the northern latitudes.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Why the output voltage from a transformer is zero if a direct current flows through the primary coil?
A transformer relies on AC current flowing through the primary to set up changing magnetic fields in the core. The field flows through the core and in to the secondary of the transformer, generating an AC current. The current must be AC, otherwise the magnetic field in the core of the transformer will saturate. In the same way, the armature of a dynamo or alternator must be moving in order to create a changing magnetic field to create current through the windings.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
What kind of electricity that flows through the electric flat iron?
Alternating current flows through a flat iron.
