This is because it is acting like a transformer. A transformer is made by tightly coiling insulated wire neatly in parallel around a rod or tubing, and it generates a lot of heat. One of the worst things you can do is to use an extension cord while it is still neatly rolled up around a core of a drum. It is then behaving like a transformer and the lead cord gets quite warm. The reason extension cords should not be used while coiled is that the heat melts the plastic insulation around the cord, the now-bare wires short-circuit, and it will explode . Uncoil extension cords before you use them.
What else can I help you with?
The tightly coiled tube that leads to the vas deferens is the?
Epididymis !!
How can you find more information about extension leads?
Information about extension leads (or cords) can be found Wikipedia, ask or eHow. Extension leads can be purchased on websites such as Amazon, Shop 411 or eBay, information can also be found on these websites.
When power tools are not in use they should?
They should be carefully placed on a shelf,with blades covered and leads coiled.
Why shouldn't you overheat extension leads?
To prevent the risk of melting the insulation and creating a short circuit and possibility a fire.
What fuse do i use for an extension lead?
For an extension lead, you typically use a fuse rated at 13 amps, which is standard for most household appliances in the UK. However, if your extension lead is designed for lower wattage devices, you might consider a smaller fuse, such as a 5 or 10 amp, to prevent overloading. Always check the manufacturer's specifications for the extension lead to ensure you are using the correct fuse. Additionally, ensure that the total load connected to the extension lead does not exceed its rated capacity.
What is the resistance of two extension leads of 95 ohms and 75 ohms when connected together in series?
The resistance across both leads would be cumulative. 95+75= 170 Ohms
What does the combination of a magnetic field and a coiled wire to create?
The combination of a magnetic field and a coiled wire can create an electric current through electromagnetic induction. When the magnetic field changes within the coil, it induces a voltage that leads to the flow of current within the wire. This phenomenon forms the basis of how generators produce electricity.
What effects does shortening the electrode extension have on weld penetration?
Shortening the electrode extension typically reduces weld penetration. This is because a shorter electrode extension results in a smaller arc length, which reduces the heat input into the weld and leads to less penetration. It is important to maintain the proper electrode extension to achieve the desired weld penetration.
When not in use hand-held electric power tool should be?
Placed its proper casing after thorough cleaning.
Which part of sound wave has molecules that are tightly packed together?
The compression or crest of a sound wave has molecules that are tightly packed together, which leads to higher pressure and increased density compared to the rarefaction part of the wave.
Why are wars good ways of resolving conflicts between countries?
War is an extension of the political process and often leads to peaceful negotiations .
Does leaving an extension lead in waste electricity?
Leaving an extension lead plugged in can waste electricity if it has devices connected that are in standby mode, as they may continue to draw power. However, if no devices are plugged in, the extension lead itself typically does not consume electricity. To minimize unnecessary energy use, it's best to unplug extension leads when not in use, especially if they have connected devices.
