The hot wire's cover is smooth and connected to what I call the "button" at the bottom of the socket. The neutral wire's cover has ridges and is connected to the screw shell of the socket.

Should grooved wire be connected to white wire?
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
What wire is the ribbed wire on an extension cord?
The only cord with a rib identifier is lamp cord. There are small extension cords made of this material but should only be used for very light duty such as extending table of floor lamps so that they can reach existing wall receptacles. This rib identifies the neutral conductor so that the lamp get wired with the correct polarity. The rib connects to the plug's neutral blade (silver screw). At the lamp end the rib wire connects to the lamp holder's shell. The shell is the part that the light bulb screws into.
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.
When removing an electrical plug from its socket grasp the electrical cord?
Do not remove any electrical plug by grabbing the wire. This weakens the connection at the plug. ALWAYS grab the plug itself when removing it.
Where is the position of black wire in electric socket?
In a household circuit, with a "hot" conductor insulated black and a white neutral, the black wire should connect to the center terminal of the socket. The outside part of the socket usually has a brass screw (for the black wire) and a nickel screw (for the white wire).
Does french lamp wiring for a crystal lamp mean that the plug wire comes directly out of the socket rather than running through the base?
The cord is attached under the shade and runs outside the lamp along the back
Is ribbed wire black or white?
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
What is the lamp black wire with white stripe?
If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
What type of conductors shall be used for wiring on fixture chains?
The type of wire you are looking for is called lamp cord. It comes in different colours usually to match the fixture. Fixtures hanging from chains use a clear insulation so as to blend in with the fixture chain colour. Remember that the smooth wire of the lamp cord connects to the hot wire and the ribbed wire on the lamp cord connects to the neutral wire in the ceiling junction box.
Which is hot ribbed wire or smooth wire?
In North America the neutral has to be identified as such. On a lamp cord the ribbed insulation side is the identification of the neutral wire. The "hot" conductor of the lamp cord is the smooth insulation.No. Screw material is no safe indicator because they would be too easy to swap round.
How to Rewire a Lamp?
The light socket normally connects to the wire by means of two screws which when screwed in will press the wire down onto a copper contact plate. Strip about an inch, possibly two inches of insulation off the end of your new wire, connect it to the socket, thread it through the lamp (every lamp has its own particular structure, but there is always some kind of hollow space through which a wire can be pulled) and behold, you have rewired your lamp.
Why does the current change at an extension plug when connected to a lamp?
Are you saying that you plug in a lamp and another lamp on that extension cord goes dimmer? If so then the extension cord wire is of a smll guage size and causing a voltage drop from the outlet to the cord output.
How do you wire a light socket that does not have side screws to attach the wires to The wires go into little holes underneath on the bottom of the socket?
These types of lamp sockets are known as pigtail sockets. Used in lighting fixtures they can not be repaired unless you have the means to re tighten the rivet that is used in the bottom of the lamp base. Any lighting store will have replacement parts for these types of fixtures. Molded pigtail lamp holders are used for temporary lighting in the construction trade. These lamp holders are positioned on brewery cord and can be placed at any needed position on the cord.
Is ribbed wire hot?
No, the ribbed conductor on lamp cord is the identified conductor thereby making it the neutral wire.
What is the amperage rating of lamp cord?
Lamp cord is #18 in size and is rated for 10 amps. This type of wire is strictly for use on lamps only and not to be used for power wiring.
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.
Lamp that has a base lamp on it and you need to wire in a top three way bulb?
The question isn't very clear, so if I'm not answering it correctly you might want to be more specific in your questioning. Make sure the lamp is not plugged into an electrical source before starting the directions below: It sounds like you have a lamp, maybe it has an existing socket or not? But the socket (where you screw the bulb into) is the part of the lamp that will determine if it is going to be three way or not. If you have an existing socket, remove it by loosening the set screw at the bottom, the it will probably be screwed to a shaft, so rotate the socket counter-clock-wise, as the base is separated from the socket, you can remove the wires from the socket by either cutting them or removing the bottom portion of the socket to gain access to the screws where the wire is fastened. Then simple attach the wires to the 3-way socket and reverse the steps above.
