The extension cord was invented in 1904 by S. W. Atherton, an American inventor and electrical engineer.
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.
A 25 foot cord will not cause enough voltage drop to worry about.
When the outlet is more than 40 feet away, or when you are operating 2 or more tools from it.
It depends on the extension cord but I will give you 2 ways and they are each very simple. On a residential type (what I call a house burner) extension cord with just 2 conductors, you will find that the jacket of one wire is smooth and the other one has ridges. The one with ridges is your neutral or white conductor. On a more commercial type extension cord with conductors covered by a protective jacket, your conductors in the cord will be color-coded, with black being hot, white being neutral and green or bare being ground.
Extension cords are not used at 5500 volts.
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.
To answer this question more information is needed. The wire size of the extention cord is needed.
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.

Extension cord???
No, the 220 v and 110 v systems are designed to use a different pin layout for the plugs and sockets, to avoid possibly dangerous cross-connections. The two voltages can not be mixed and equipment for one system cannot be used on the other without a transformer.
Yes, there are outdoor extension cords that are specifically designed to be used outdoors. These cords have a more durable construction and are typically weatherproof or water-resistant to withstand different outdoor conditions. They are often made with thicker insulation and have specialized plugs and sockets to ensure safety in outdoor settings.
normaly we can use water proof extension cord
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 extension cord holder is used to hold an extension cord. It wraps around the holder, for easy release and withdrawal.
Yes, it safe to touch a extension cord while its plugged in.
