![]() ![]() In some instances, black can suggest sophistication and power, while in other cases it can be seen as dark and gloomy. Generally, black is neither positive nor negative as it is a neutral color and can connote many different meanings depending on the circumstances. The answer to this question depends on the context. If A and B represent two concepts or objects, then a positive concept or object could be defined as one that has benefits or is advantageous, while a negative concept or object could be one that has drawbacks or is disadvantageous. If A and B represent two numbers, then a positive number would be one that is greater than zero and a negative number would be one that is less than zero. The answer to which one is positive, A or B, depends on what A and B represent. Therefore, it is important to always consult a qualified professional electrician if you are unsure of how to correctly wire your lamp. Additionally, if the lamp has multiple switches, it is important to determine which switch controls the upper half of the lamp and which switch controls the lower half of the lamp to ensure correct wiring.Īll of these wiring decisions are important for safety reasons, as improper wiring can lead to electric shock, damage to the lightbulb, and possible fire hazards. It is important to know the type of bulb and wattage that you have in the lamp in order to determine the correct wiring inside the lamp. The correct installation of a lamp socket is determined by the type of socket you are using as well as whether or not the lamp is controlled by a switch. Yes, it does matter which way you wire a lamp. Does it matter which way you wire a lamp? Finally, check in the lamp’s owner’s manual to be sure you have the polarity correct. If it reads negative, then it is the negative wire. If there are no markings, you can also use a small voltage detector or multimeter if you have access to one.Ĭonnect one of the probes to each wire and if the detector reads a positive voltage, then the wire it is connected to is the positive one. The other wire is usually bare or smooth, and this is the positive wire. Then, look for markings on the wires themselves – many cords will have one of the wires marked with a stripe or a textured surface. To determine which wire on a lamp cord is positive and which is negative, start by locating the two wires coming out of the cord. ![]() How do you tell the positive and negative on a lamp cord? Look for the images of a “+” or “-” sign or the words “Positive” and “Negative” on the plug to determine the positive and negative sides of the cord. It is important to identify the positive and negative sides of a cord before connecting it to any electrical devices to avoid damaging the device or causing injury to yourself or others.Īdditionally, the plug itself usually has a labeling on it showing the positive and negative sides of the cord. The side of a cord that is positive can be identified by the presence of a red or brown wire, while the side of a cord that is negative can be identified by the presence of a black or blue wire. Which side of cord is positive and negative? To confirm, you can use a voltage tester to verify which side is hot. The wire with the smooth surface or writing that reads “Hot” or “Live” is the one that is hot. One of the wires will have ridges or have an indentation in its plastic coating, while the other one will have a smooth surface. When the power is off, you should identify the two wires of the lamp cord. Make sure you turn the power off before working with the cord. To be sure, you should use a voltage tester to confirm the correct side. ” The universal warning symbol of a circle with a line through it is often printed near the Hot side. The side of the lamp cord that is hot is the side identified with a smooth surface or writing that reads “Hot” or “Live. How do you tell which side of the lamp cord is hot? If the wires are reversed, the lamp may not light up or may not function properly. To properly install the lamp cord, connect the black side to the negative (–) terminal, and the white side to the positive (+) terminal. It is important to make sure you are connecting the cord to the lamp in the proper manner. ![]() The black side is usually the negative side, and it is marked with a minus (-) symbol. The lamp cord typically has two sides, a black side and a white side. ![]()
