If the voltage is doubled the ampacity of a conductor is?
Unchanged. The conductor's ampacity is affected by its composition (copper, aluminum, etc.), cross-sectional area, and temperature, not by the supply voltage. The ampacity is limited because any conductor has resistance. When the conductor carries a load (supplies current), the conductor essentially becomes a resistance heater, and gets hot. At some point the temperature will become dangerous, either causing the conductor to melt or damaging the insulation or surrounding materials. The voltage dropped across a conductor that is supplying current to a load is computed by the following formula: E=I^2 X R Or, voltage dropped equals current through the conductor squared times the resistance of the conductor. Notice that the supply voltage is not even part of the equation. All the mentioned parameters - composition, cross-sectional area, and temperature affect its resistance. The ampacity of a conductor installed in a building can also be regulated by law, so, even though a conductor may pass a certain amount of current local laws may prohibit it's use anyway.
What determines the maximum current that can be carried by household wiring?
The capacity, known as the wire's ampacity, of the wire to carry amperage safely determines the size of the wires used in house hold wiring. This capacity is stated in the electrical code that is used in different countries around the world.
How many watts can go through 22AWG wire and do the amps and volts matter?
Wire size is rated in Ampacity, so yes, You have to divide watts by the voltage to give you the current (Amps). Strange question, the only use for 22AWG wire that I know of is analogue control, 24 volts, 4-20mA. 22AWG is not even listed in the NEC as a Current Carrying Conductor.
What determines the ampacity of wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.

What is the ampacity of gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
What is the final ampacity for a number 12 NM-B conductor?
What is the final ampacity for a number 12 NM-B conductor? Answer this question…
The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?
No. The larger the conductor the lower the resistance and the higher the ampacity.

Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
What is Wire ampacity?
It is a North American electrical term. It is a combination the words amp and capacity rolled into one word "ampacity". When talking about how much amperage a wire can legally draw, it is referred to as the wire's "ampacity".
