A red and black and white are now connected to the terminal strip. Look at the position and colours of the existing 3 prong cord and how it is connected. Make a diagram. Coloured wires on the outside terminals white in the center. From the center wire terminal you will see a jumper strap that goes to the frame of the dryer. When installing the four prong plug this jumper is removed completely. The kit should have with it a grounding lug that connects to where the removed grounding strip attached to the frame of the dryer. This is the attachment point for the fourth green ground wire from the new dryer cord assembly.
...worn to the point that bare copper wire is exposed, not frayed, not otherwise damaged. You could also check the temperature of the cord to make sure it isn't hot to the touch and make sure the plugs, sockets and connectors are not loose and the the connection points are undamaged. Often people cut off the third grounding prong in an appliance cord when they don't have the proper grounding outlet.

The extension cord will extend the power outlet from a wall socket. The voltage will be the same at the end of the cord as it is from the socket. Be aware that extension cord may have a limit, as to how much current it can provide. The cord should be thick enough to provide as much power as the outlet can. It will then be properly protected by the circuit's fuse or breaker. A thin cord may get hot if a large consumer is plugged in, unless the cord is protected by it's own fuse at the plug end.
If the computer is connected by a USB cord to a powered USB switch, then many connections can be made.
I would not recommend trying to use an extension cord for a dryer. the better option is to either buy a longer cord that is properly sized to deal with the extra distance or have an electrician come out and either move the outlet or custom make you a longer cord for your dryer.
It is like an extension cord for under cabinet lighting. Some lighting packages come with interconnecting cords that are too short for the cabinet layout to make placement look symmetrical. These cords can extend the range between the fixtures for placement of the fixtures where you want them to go, not where the manufactures length allows them to go. Make sure that you match the linking cord to the same manufacturer as the fixture so as to allow the socket ends will match.
