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.

Moving a conductor through a magnetic field will produce alternatinc current (AC).
A: Believe it or not that what a transformer does
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.
An ampacity is the root mean square of the electrical current which a device can carry within a specific environment, measured in amperes.
double if resistance is considered same.
No. The larger the conductor the lower the resistance and the higher the ampacity.
What is the final ampacity for a number 12 NM-B conductor? Answer this question…
The conductor's insulation can melt if the current gets higher than the ampacity of the conductor.
Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor. A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.
well if you doubled the coils it would be pie times the amount of voltage in the current squared
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
The battery is the voltage or power source, the wires form the conductor.
Ohm's law states that the voltage across a resistor is the product of the current times the Resistance or V=I x R (I times R). V is Voltage, R is Resistance, and I is Current or Amperage. So if the Voltage is doubled and Resistance stays the same, the Current will be doubled.
It is halved. coz voltage=current * resistance
The battery is the voltage or power source, the wires form the conductor.
