Why is there only one wire a dynamo lamp?
I'm guessing that you're talking about a bicycle here... They can get by with only one wire, as the steel frame and fork of the bicycle is used for the return path.

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 device changes mechanical energy to electrical energy by roatating a coil of wire througha magnetic field?
Such a device is called a generator, or a dynamo.
How electricity generated in dyanamo?
A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.
Can you convert rotational motion of a bicycle wheel into electrical energy?
Yes, it is possible to convert the rotational motion of a bicycle wheel into electrical energy using a device called a dynamo. A dynamo is a small generator that contains magnets and a coil of wire. When the bicycle wheel turns, it spins the dynamo, generating electricity that can be used to power lights or charge batteries.
How do you make simple dynamo to glow a bulb?
By attaching a fan in the dynamo and rotating the fan and connecting one end of wire in the dynamo and another end in a bulb which helps in glowing of bulb by using the power of dynamo.
What is the minimum wire size for desk lamp cords?
Most lamp wire is parallel #16 conductors.
What is a difference between motor and generator?
A generator uses the rotation of a coil of wire in a magnetic field to generate an electric current (also known as a dynamo), while a motor uses electricity flowing through a coil of wire placed at right angles to a magnetic field to produce rotation of the coil. Look up Fleming's left and right hand rules in a Physics textbook for further information.
What is a loop or cool of wire that can rotate?
AC and DC Dynamo, galvanometers, etc...
Where can one find out how to rewire a standard lamp?
eHow is a great resource for topics like this, with articles like "How to Re-Wire a Lamp," "How to Rewire a Lamp with a Rotary Switch," "How to Rewire an Old Lamp," and "How to Wire a Floor Lamp."
How do you wire a bicycle dynamo?
EASILY. jUST THREAD THE WIRE THROUGH THE HOLES AS SHOWN IN THE INSTRUCTIONS THAT YOU CAN GET POSTED TO YOUR POSTAL ADRESS.
