I was at Sears Hardware yesterday and bought 50 feet of flat wire for 99 cents. It was in the clearance section and I figured, ah, what the heck.
It's rated at 300 ohms. I am trying to figure the maximum wattage this thin wire can handle by using the following formula:
W=I X V ; V= I X R ; therefore W= I X I / R
Since the output voltage is 120 volts and the resistance is 300 ohms, then W= 120 X 120 / 300, which calculates to 48 Watts.
Anything wrong with my assumptions?
