wire size related to wattage R=I/V

[Anonymous]

What is the related maximum wattage to (copper) wire-size when voltage is assumed at ~120 USA?:
<> 10 ga
<> 12 ga
<> 14 ga

I'm not sure what V=IR has to do with wattage in this case, but I'll try to answer.
#14 is generally associated with a 15A circuit, which can be loaded continuously with 12A. The simlified formula for Watts is W=12*120 or 1440Watts for a 15A circuit (#14 copper wire).

Similarly, #12 awg copper, 20A circuit, 16A, 1920 Watts and
#10 awg copper, 30A circuit, 24A, 2880W

To find Ohm, you can calculate in these three manners:

1. R=E/I

2. R=E to the second power/P

3. R=P/I to the second power
