Because rubber does not conduct electricity
I had same problem, it ended up being a broken wire that runs between the door and the body of the car inside a rubber cover. Easy fix too, remove the rubber sleeve, cut the wire, strip the ends of the two wires and use a butt connector to rejoin them.
No not suppose to use them together.
It is not 'insoluted wire'. That one in named as ' insulated wire' Usually metallic wire carries the current. Just to avoid electric shock it is to be covered by insulators such as rubber or plastic. Some times we use nickel coating which also serves the purpose of insulation.
copper plated aluminum wire
If you insist on removing the rubber coating on a wire chemically, try using acetone. Otherwise, throw it in a fire or use old fashioned wire strippers.
Yes, but you have to do it correctly. You should use 10 AWG wire. The splice should be in an approved electric box using the right size wire nuts. You secure and protect the extended wire and you should not "bury" the splice box in the wall, but cover it with an approved cover made for the purpose. If it is a surface mount box, cover it with a blank metal cover.
cos rubber is an insulator and will protect you
The main use of lead wire is as connection to an electric pole of an electronics component.
Yes it can. I use flux core wire because there is no need for gas with flux wire.
we use resistors in an electric circuit to describe how a wire works and to control the flow of electricity
meters, yards, or feet
Wire closet shelving is usually coated with a plastic lining. Some of them use rubber.
