What else can I help you with?
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
How does an electric generator generate an electric current The generator?
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
What does a conductor do in a dc generator?
It is a conductor, it conducts the electric current generated to the load that is being supplied with power.
A 105V generator delivers 25KW to an electric furnace What current is the generator supplying?
Power = E I25,000 = 105 II = 25,000 / 105 = 238.1 Amp
What electric current is produced when a spinning shaft rotates magnets inside a generator?
direct current
How can you increase the amount of electric current produce by generator?
To increase the amount of electric current produced by a generator, you can increase the rotational speed of the generator, increase the strength of the magnetic field within the generator, or increase the number of turns in the generator coils. These methods will result in a higher induced voltage and therefore a higher electric current output.
What is a device that changes motion into electricity using magnets and spinning coils of wire?
That would be an electric generator. They are also called dynamos. An alternator is a type of generator that makes alternating current.
How do you store the 30 volts produced from spinning an electric motor?
A motor can be connected up to a car battery to store the power produced when it runs as a generator, but you will find that when current is drawn the motor needs more work to spin it, it will not spin so easily. That is because of conservation of energy.
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.
Controls the flow of electric current?
a generator
Why does a generator work?
When a conductive loop is moved through a magnetic field, an electric current is produced in the wire loop. This is the basis of electrical generators.
What causes an alternating current in a generator?
The spinning magnet in generators.
What is the electricity from a simple generator?
Electricity from a simple generator is produced through the principle of electromagnetic induction. When a conductor, such as a wire coil, moves through a magnetic field, it generates an electric current. This current can then be harnessed to power electrical devices.
Does an electric generator motion produces magnetism or power or electricity?
An electric generator produces electrical energy. It converts mechanical energy to electrical energy by interacting with a magnetic field. The amount of electrical energy converted to useful work in a given time interval is the power output. If the generator is not connected to any load, then no work is done and there is no power.
How you can store electric current which is produced from ac generator?
First ac has to be rectified into dc and then that could be stored in a secondary cell in the form of chemical energy.
In a modern coal fired electric plant the mechanical energy of turbines is tranformed into electrical energy by?
The mechanical energy of turbines in a modern coal-fired electric plant is transformed into electrical energy by spinning a generator. The generator works by using the rotating motion to induce an electric current in coils of wire, in accordance with Faraday's law of electromagnetic induction. This current is then converted into usable electrical energy that can be distributed to power grids.
