The speed of rotation and the strength of the magnetic field.
Small dynamos used on cycles are unregulated and the voltage will continue to rise with speed.
Car dynamos are regulated by varying the current in the fied windings, to keep the voltage no higher than 13.8v, regardless of the engine speed.
What else can I help you with?
What is alternating current produced by?
Alternating current is produced by generators or power plants that use magnetic fields to induce voltage and generate electricity. This type of current changes direction periodically, typically in a sinusoidal waveform.
How much electricity does dynamo creates?
A dynamo generates electricity through electromagnetic induction when mechanical energy is applied to it, typically converting mechanical energy into electrical energy. The amount of electricity produced depends on factors like the size and design of the dynamo, the speed at which it is operated, and the efficiency of the conversion process.
Why is there only one wire on a dynamo lamp in a wind turbine?
The single wire in a dynamo lamp is typically used to connect the lamp to the output of the dynamo, which generates electricity from the rotating movement of the wind turbine's blades. The lamp can be illuminated when electricity is produced by the dynamo, providing a source of light powered by the turbine's energy generation.
How can the energy produced by the dynamo be stored?
The energy produced by a dynamo can be stored in batteries, capacitors, or through other energy storage systems like compressed air or mechanical storage. These storage systems can hold the generated energy for later use when needed.
What energy transformation is in dynamo?
In a dynamo, mechanical energy is transformed into electrical energy through electromagnetic induction. Rotation of a coil of wire within a magnetic field generates an electric current as the magnetic field induces a voltage across the coil.
Suggest three ways to reduce the voltage produced by a dynamo?
1. Reduce the rotational speed of the dynamo. 2. Place a 'dropping' resistor in series with the load. 3. Vary the field strength of the exciter in the Dynamo.

Dynamo

Would a dynamo still work if the coil of wire was rotated and the magnet stayed still?
Yes. The voltage produced is the effect of the relative motionbetween the two, so it doesn't matter which one is moving.
How do you charge a battery using dynamo?
A "Dynamo" is a DC charger; these will overcharge any battery there is and requires a regulator circuit, they will produce voltage proportional to their rotation. Simply hook it to the battery (watch your positive and negative) and crank the generator / dynamo.
How can you build a dynamo for producing electricity?
A dynamo uses the same physics as an electromotor. Get yourself any electromotor. Spinning it will generate some AC voltage at the power supply contacts.
How do you get more power from a dynamo?
Assuming you mean on a bicycle, Screw in bulbs that need more voltage, but the same current.
Where does the voltage come from in an electric circuit?
Depends on which circuit. It can be from a battery, or a device called a generator, alternator, dynamo, or a magneto.
How do you make a dynamo?
To make a dynamo, a small hobby motor is needed. The small hobby motor is then mounted on a board of wood and then connected to a bigger wheel. The handle is then fixed and the motor connected to a voltage regulator.

How to adjust a dynamo voltage regulator?
Avoid the problem and fit a solid state regulator. For example view www.manortec.co.uk/dvr.htm
