If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
White is neutral in home wiring. Red is sometimes used in 3-way switches and dimmer applications, so it is likely red is hot in your application if it pertains to home wiring. The term positive would just apply to DC wiring since AC goes positive and negative. For example your car battery has Red as Positive and Black as Negative.
Ribbed wire typically comes in black color for easy visibility and identification. However, it can also come in white or other colors depending on the manufacturer's specifications or application requirements.
Yes, the green conductor is the colour of the ground wire in an extension cord. The black wire is dedicated to be the "hot" and the white conductor is the neutral.
Depending on the configuration of the cord cap, the green wire is ground, the white wire is the neutral and red and black wires are the 220 volt source.
To splice a cord with white and black wires to a cord with red, green, black, and white wires, first ensure that both cords are unplugged and safe to work with. Connect the black wire from the first cord to the black wire from the second cord (which is typically the hot wire). Connect the white wire to the white wire (the neutral), and if applicable, connect the green wire (ground) to the ground wire (if present). The red wire is often used for a second hot wire or switch leg; ensure it is capped off safely if not in use. Always use electrical tape or wire connectors to secure the connections and ensure safety.
Flexible cord colours are, White for neutral and Green for ground.AnswerIt depends on the standards used in your country. The above answer refers to North America. In Europe, the colours are brown for the line (not 'phase'!) conductor, blue for the neutral conductor, and green/yellow stripe for the earth (ground) conductor. For European three-phase systems, the lines are coloured brown, black, and grey.
Black is the hot side of the line, white the neutral side, green (or rarely bare) wire is the ground.
On a molded 2- or 3-wire line cord the ribbed conductor is the neutral conductor. On a polarized 2-prong plug it will be connected to the wider blade. On some line cords the neutral conductor may have a white stripe instead of ribs.
This will not work. Your neutral blade is gone. You need both for it to work.
A four blade dryer plug cord should have a red, black, white, and green wire in the cord set. The red and black wires are the ones that deliver the 240 volts to the dryer. Black and white deliver control 120 volts to the dryer and also drive the motor to turn the dryer drum. On some dryers they use the red and white for the motor and black and white for the control. As for the green it is always the ground 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.
