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.

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 power an outlet from a one wire light switch on same wall?

The one wire carries the electricity or voltage. The lamp is grounded completing the circuit. You don't. The light switch is only half the circuit, a lamp has nothing to ground to so it can not work. If the wire to the switch is 3 wire, the bare wire would complete the circuit and power the plug, but it would not be up to code and could present a fire hazzard.


How do I re-wire the 3 wire rotary switch to the two socket swag lamp correctly?

One wire is the hot off the plug, one is the hot to one socket, and the third wire is the hot for the second socket. You'll have to check the switch for the exact color code / which wire is which (I don't know if there is a standard). You can test it easily with a multimeter as well.


How do you wire a tri-light bulb table lamp with 3 wire rotary switch?

If the tri-light needs a new lamp holder try any reputable lighting house store. These types of retailers have all of the parts that you need to repair any lamp configurations. The new switch will have a rotary switch built into it just like the lamp had when it was new. There are only two wires to connect to it. Don't disconnect the old one until you have the new one and just put the wires on the same terminals as the they are wires on the old switch.


Is plus or Minus Ground on lamp socket?

The term plus or minus is usually a term designated to DC Sources. The terminology for AC systems in laymen terms is neutral and "hot". On a lamp socket, for safety reasons the lamp shell should be connected to the neutral wire and the "hot' wire connected to the bottom centre contact point. In North America this is done automatically by connecting the white wire the silver coloured terminal and the black coloured wire to the brass coloured terminal. If the lamp socket is on a table lamp and it is wired with lamp cable, the neutral is identified by the raised rib on one of the two wires.

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.

No he has two legs or he would'nt be able to do the Dynamo shuffle.(Plus he walks with swag)


How do you fit a dynamo on a bike?

Depends on the type. A regular bottle dynamo will come with an assembly bracket that'll either clamp on to one of the fork legs, or one of the seat stays. Then you just have to wire it up to the light(s).

How do you identify the NEUTRAL wire on a 2 wire very old electrical cord of a goose neck lamp?

The best way to find the neutral wire on any lamp is to ring the wire out. Before there were polarized plugs and receptacles a lamp could be plugged in either way. All new lamps have polarized plugs where the neutral is connected to the shell of the lamp holder and the "hot" wire is connected to the center pin deep in the lamp socket. Back to your goose neck lamp, you will need a meter that reads resistance and use it as a continuity meter. With the lamp unplugged and the lamp's switch in the off position connect one lead of the meter to the shell of the lamp holder. Take the other lead and touch it to one of the plug cap blades. If the meter gives a reading it is that blade that is the neutral wire. If there is no reading then that blade is considered the "hot" wire. If you are changing the plug (cap) out for a new one connect the newly established neutral wire to the silver coloured screw and the newly established "hot" wire to the gold coloured screw. Now when ever and where ever the lamp is plugged into a voltage source the polarity will be correct and the lamp will be much safer to use.

Can electricity be regenerated by connecting electric motor to a dynamo?

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.....
