The extension cord was invented in 1904 by S. W. Atherton, an American inventor and electrical engineer.
Almost all my life I have used electric power tools with extension cable. I have never found it "unsafe" or ever had any incident with that. - Probably just more garbage coming from 'teachers' who think they know more than those of us who just 'do it' knowledgably and safely !Another AnswerWell, speaking as a 'teacher', I agree that it is quite safe to use an extension cord with a power tool -in fact, that's what extension cords are for and it's probably safer than just using the limited amount of cord permanently connected to the power tool itself. There are some provisos, however; for example, if the power tool has an earth (ground) conductor then so, too, must the extension cord. And the current-carrying capacity of the power cord must equal or exceed that of the power tool. And it's best not to leave the extension cord on the reel due to the resulting increased inductance and lack of cooling. And, of course, there's the obvious safety requirements -don't drill or saw through it, or drape it is liable to become damaged or where people are liable to trip over it, etc.
I don't know about the warranty, but the unit will run fine using an extension cord IF you buy one that is heavy-duty. Look for a cord that is 12 gauge or even 10 gauge. If you use a 14, 16, or 18 gauge cord (these may be too small), the unit could be damaged.
You can rewire your extension cord by replacing the existing wire with green, black and white wires. In most situations it is safer and cheaper to buy a new extention cord.
When the outlet is more than 40 feet away, or when you are operating 2 or more tools from it.
No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.
An appliance which does not use much current will perform satisfactorily with a long extension cord. Any device which uses a lot of power (space heater, large power tools) will not perform well on a long ext cord unless the cord is large enough and rated to carry the required power.
An extension cord is a long power cord that plugs into an outlet and receives with an outlet. A computer cord just uses one long cable to transfer power to the computer from the outlet.
Yes. It should be a 'heavy-duty' extension cord, rated for 15A or 20A .
Any extension cord that has the capacity to carry the amperage that the TV draws. Any extension cord that the hardware store sell will be sufficient to do the job.
There aren't any fuses in extensuion cords. You have a bad or broken connection somewhere in that extension cord. Not a short -but an open connection.
You can, but the length of the cord changed the power it provides. The longer the cord the greater the power loss.
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.
If there is no load plugged into the cord there will be no power consumed. The only time the resistance of the cord will come into effect is when the circuit becomes energized through the load plugged into the end of the cord.

Yes, the higher quality of the two extension cords is the one rated for outdoor use.
Short electrical cords are less likely to get tangled, to get tripped over, to get stepped on which can cause fraying, or to otherwise be messy and troublesome. Of course, if you don't happen to have a conveniently located electrical outlet, your short cord won't be that convenient after all. But you can always use an extension cord or power bar if you need to.
