In order to generate an electric current, a magnet is moved near copper, usually copper wires. Because of the magnetic field affecting the copper, an electric current is formed due to the electrons moving in the copper.

∙ 13y agoGenerators produce alternating current (AC). The smaller ones generate single phase AC, but any larger one on the power grid will generate 3-phase AC. There are some DC (direct current) generators, but they have devices inside them (perhaps rectifiers of some sort) that change the AC into DC. Some polyphase generators can be found in , but most of the generators that "make power" for electrical applications are the 3-phase AC kind.
It might be noted that the currents produced by a three-phase generator are 120 electrical degrees apart and have a sinusoidal waveform. And on the US power grid and some others, these generators generate 60 Hertz (60 cycles per second) AC, while in other parts of the world, 50 Hertz (Hz) can be found.

What is an ac and DC generator?
An a.c. generator produces alternating current, whereas a d.c. generator produces direct current.
What is Faraday law of a DC generator?
Faraday's law : If a "conductor" is placed in a "magnetic field" the movement in either conductor or field produces an induced emf in the conductor. In generator the produced torque will be in AC(alternating current) so commutator or slip rings is used to produce unidirectional torque required for production of Direct Current. Basically by Faraday law the produced torque will be always bidirectional, for alternator the bidirectional torque can be used directly. for DC generator the unidirectional torque is needed to produce Direct Current.
Which is usually produced by a generator ac or DC?
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
What is the caused of unbalance of current during parallel running of two generator?
That depends on if the two machines are of equal KVA rating and also what type of Generator Control (Isochronous or Droop) each of the machines uses.
What is meant by Generator P.f?
the cosine of the angle between voltage and current of generator is called power factor (pf) of generator.
What energy is made by a generator?
Depending on the type of generator: Electricity in the form of direct current (DC) or alternating current (AC) is produced.
Alternating current is produced by battery or generators?
A generator produces alternating current.
What is the relationship between the speed of a generator and its voltage and the torque on the generator shaft and the current produced by the generator?
emf produced by generator(E)=no. of turns in coil*rate of change of magnetic flux
What is relation between speed of generator and its voltage and torque on generator shaft and current produced by generator?
power = torque * rpm
What electric current is produced when a spinning shaft rotates magnets inside a generator?
direct current
What type of signal is produced by an inductive generator?
AC sinewave
How AC current is produced?
UK mains ac current is produced from a rotating 3 phase generator, rotating at 50 cycles per second (50 Hz)
Electric current is produced when a spinning shaft rotates magnets inside a generator?
The process in which electric current is produced when a spinning shaft rotates magnets inside a generator is referred to as 'Direct Current'. It is not expected to work by the normal standard physics model however some people claim it is just.
What type of signal is produced by an inductive pulse generator?
AC sinewave
When the wire loop of a generator turns an electric current is produced?
The flux density of that coil becomes greater.
When sea water freezes which type of current is produced?
a surface current forms
What is the type of generator protection to protect against unequal phase current?
differential protection
