You are talking of two different things here. The voltage rating of a wire is based on the insulation factor. Common wire voltages are 300, 600 and 1000 volts. Current rating of a wire is based on the diameter of the wire and measured in AWG. The electrical code states how much current can be legally applied to the wire. Answering your question, the 2 wire cable is probably 300 volt rated and your #14 size wire is rated at 15 amps. Code also states that conductors can only be loaded to 80% continuous load, so 15 x .8 = 12 amps.
one strand of 14 guage wire is designed for 110-120 volts.
A #14 copper wire is rated at 15 amps maximum.
20
That is 10 amp wire.
10
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
Yes you can. That being said the different wire size that is to be used can not have a smaller current capacity than the breaker that is supplying that circuit. In other words the wire size that is added to the circuit has to be larger not smaller. For example a 20 amp breaker can have a #12 at 20 amp rating, #10 at 30 amp rating or a #8 at 40 amp rating added to the circuit but not a #14 which is only rated at 15 amps. Using 15 amp wire on a 20 amp breaker could overload the capacity of the #14 wire which is rated for a maximum of 15 amps.
250 amps maximum.
That is 10 amp wire.

Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
There is insufficient information. If this is question about a dryer or stove, please specify.
Depends on the rms or continuous rating of the amp and at what ohm is the amp stable
Under normal household conditions it is 15 amps.
