A perfect wire would have no resistance, but we don't live in a perfect world, so they do. Anything that creates electrical resistance ends up turning some of that resistance into heat. The plug of a cord tends to have more metal (hence more resistance) than the rest of the wire, so it gets relatively hotter.

∙ 11y agoBecause there is electrical current running through the wires and connectors, each of which have resistance, thus dissipating some amount of power as heat.
Under ordinary use, no appliance plug should get overly hot. If something is too hot to touch with your bare hands, something is wrong and it should be switched off and disconnected until the problem can be found.
North American plugs tend to get much hotter in use, compared to European plugs, because European plugs -particularly British plugs- use pins with significantly-large cross-sectional areas.
In my experience, a British plug doesn't even get moderately warm -even when supplying a 3-kW load, whereas I have had Canadian plugs that are quite warm even when supplying an electric drill load!

Is the ridged wire positive on an extension cord?
An extension cord that you plug into your house is neither positive OR negative. It uses alternating current so there's a live wire and a ground. Only direct currents (like those in cars) have positive and negative. On a two wire extension cord the ribbed side is the neutral. If you look close and it is a moulded plug on the end of the extension cord you will find that the side with the rib is also the same side as the wider blade on the plug. This corresponds to the wide blade hole in the receptacle which is also the neutral side of the receptacle.

What makes the electric cord on a oil base heater get hot?
It is normal for the cord on any heater to get warm after you are using it for awhile. If it gets so hot that it is uncomfortable to touch or the insulation becomes very soft, cracks, bubbles, or becomes brittle, you should stop using the heater. There may be a short in the cord, the wire inside may be partially broken in one or several spots, the cord might be cut, or the heater may be malfunctioning. For the price of these heaters it is advisable to simply replace one if it is malfunctioning. If you determine that the cord is at fault and you want to replace it, be sure to use a quality 14 gauge or heavier cord and make sure you have adequate strain relief on the cord as it enters the heater. If you buy the cord and plug separately make sure the plug is rated for at least 1500 watts or 13 amps and the new plug has the same number of prongs.
