Wire carrying negative and positive charges in a closed circuit. It doesnt have earth.
kickstart doesnt use wire to start up, thats for an electric start, you only need the battery for things like an electric start, lights etc
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.
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
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.
Polarizing or repolarizing a dynamo is a way to wake up generators that may not have been used for a longtime, may have been incorrectly wired up in the past, or are not producing any voltage for some reason. First thing to check is which battery terminal is connected to the frame or chassis of the vehicle. Modern cars & motorcycles have the negative terminal connected to the frame, this is called a negative earth configuration. For models of the 1950s and earlier, the configuration is positive earth. To polarize the dynamo for negative earth, disconnect the positive or live wire from the battery terminal at the same time making sure the negative terminal is connected to the chassis. Disconnect the wires from the D and F terminals of the dynamo and run a wire from the positive terminal of the battery and brush the other end of this wire over the F terminal 2 or 3 times until a blue spark can be seen. The dynamo is now polarized for negative earth. Do the procedure in the other way around to polarize a dynamo for positive earth.
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.

AC and DC Dynamo, galvanometers, etc...
EASILY. jUST THREAD THE WIRE THROUGH THE HOLES AS SHOWN IN THE INSTRUCTIONS THAT YOU CAN GET POSTED TO YOUR POSTAL ADRESS.
youll need to first wire up the socket to battery.
It'd be rare to have a dynamo actually IN the rear wheel, far more common to have it at the side of it, driven by pushing against the tire. The purpose of a dynamo is to provide power to bicycle lights. A bicycle dynamo functions just like any other dynamo of the same principle - expose a coil of electric wire to a changing magnetic field and you get a current out of it.
Because the chassis/frame is used for the return path.
The Earth wire is there to earth electrical devices that are not double insulated. If there was to be a malfunction in the appliance then you can get a really bad shock if an earth wire is not present. If there is any free electricity roming around then the earth wire will send it down to earth and to the main power station closest to the area instead of through your body. s aged 15
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
The question is mine......take one dynamo and a motor (both of them are DC).. If The Dynamo is 12v and the motor is 9v...and connect together.....means the rotating shaft of a motor is connecting using a belt then the other end connected to the rotating shaft of the dynamo ......connect the wire parallel......let start... take a cotton thread of 15 cm ...then round the thread on dynamo rotating shaft the pull it....the current from dynamo flows to motor that action make the motor rotates but not constant.....
no it doesnt
