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.
When you are trying to determine which wire is the hot wire then you must assume all of them are. Use a voltmeter to determine which line is hot and which is neutral. Never assume a wire is hot or not because of its identification unless you are very familiar with the circuit.
no
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
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.
Depends on the size of the wire in the extension cord. The 3 prong is just the hot, neutral, and ground.
Materials would consist of extension cord cable, male and female cap ends. The tools would consist of a screwdriver that will fit the termination ends screw configuration and a pair of wire strippers or a knife to strip the extension cord wire.

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.

If wired properly the ridged wire is the neutral.

you need to state more information but in any case yes you can.

If your extension cord is truly a 30 amp cord then it is composed of #10 wire. #10 wire is rated at 30 amps. All you have to do is remove the 30 amp plug and receptacle ends from the cord and install 15 amp cord ends.
There are several parts to an extension cord. There is the "female" end where you would plug in the appliance, the cord, and then the "male" end which gets plugged into an outlet.
