Why a dc generator you unable to generate emf even its armature is rotating?
bad connection
What device produces electrical energy?
A generator, alternator, or dynamo is a (usually)rotating machine that converts mechanical energy into electrical energy.This is the principle behind electrical generation with the windmill, hydroelectric generator, crank generator. Ocean wave generators take advantage of the vertical motion of rising and falling water to achieve the same effect.
What is alternating current and give examples for this?
Alternating Current( AC ) constantly reverses itself as a result OS reversing electromotive force.One complete reversal is a cycle,and the number of cycles per second is the frequency of alternating current .The standard frequency of alternating current in the United States and the rest of North America is 60 Hz(1 Hz or hertz,equals 1 cycle per second )ex...Transformer,AC generator
What is electrical rotating machine?
MOTOR
What is armature current according to generator terms?
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 fieldConductorMotionSo, 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 current that moves back and forth is?
Possibly, you are thinking of Alternating Current?
How does a generator produce a alternating current?
Electro-magnetic induction . a rotating force-field, so to speak. sounds very sci-Fi but a basic electrical device.
Why are currents changing direction?
Alternating current is generated by a rotating generator which moves in such a way as to produce that kind of current.
What is an AC generator?
An AC generator is an electrical machine which produces alternating current electricity. It must be turned by a prime mover which can be an internal combustion engine - driven, usually, by diesel oil or gasoline - or can be a turbine, driven either by superheated steam or by water falling from a reservoir. (The latter is known as "hydro-electric power generation").Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil. That kind of system is called an AC generator or an "alternator".An a.c. generator, which is usually called an 'alternator', is a machine which converts kinetic energy into electrical energy. Its output is an alternating voltage.For more information see the answers to the Related Questions shown below.

Which statement describes an AC generator?
AC generator is a rotating machine with a rotor and stator winding, driven by another prime mover, which generates alternating current at a specified voltage.
Why is alternating voltage induced in the rotating armature of a generator?
The windings of the armature are constantly cutting magnetic lines of force of opposite polarities
What happen if you change the connection of armeture of dc self excited generator?
the rotating will chang.but if you chang terminal connection nothing wont happen.
How does wind energy help wind turbines work?
Wind blows on a windmill or wind turbine and makes it rotate. This can be looked at the kinetic energy in the moving air being converted to the kinetic energy of the rotating vanes. The rotating turbine turns a shaft that turns (through gears) a electrical generator. The generator produces electricity. This can be seen as the kinetic energy of the rotating vanes transferred to the kinetic energy of the generator, which converts it to electrical power. The electrical power is then sent into the electric grid.
What device changes mechanical energy to electrical energy by rotating a coil wire through a magnetic field?
That's an electrical generator, whether the mechanical energy comes from steam or water flowing through a turbine, or wind, or tides.
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
How is a motor different from a generator and how is a generator different then a mot or?
A motor takes electricity and creates rotating motion. A generator takes rotating motion and turns it into electricity.
