The wire will be attached with glue. The plastic will be vertical. It will usually have around 20 miles per hour air flow on it. As for the information on the plastic, all I know is that it is a face shield for a snowmobile helmet, so whatever that makes it. Lastly, yes I plan to attach the wire...

Alright, so here are the detail I know. The length of wire I am shooting for is 10 feet. This would be attached to the surface of 1/4 inch thick clear plastic (not glass) in a horizontal pattern, this is that it would run horizontal for one foot (right) then turn vertical for one inch (down)...

Ok, I will figure those details out and get back to you. Thanks

Yes, I would like to do essential the same thing as what is on a vehicles rear window. The difference would be the length of the wire and the applied voltage. But I'm looking for it to do the same function as a window defroster.

Perhaps it would help if I told you I don't need a specific temperature. I'm just wondering how much current or voltage or watts would need to be put through a wire to maintain a temperature above freezing when the air temperature is at or slightly below freezing. Much like the defroster wires...

Nichrome 80 and it would have insulation on it.

So this method would not work with a wire that is an alloy? If not, then is the method that Chestermiller stated the only method to use? Or is there a different approach to this if I also know the current expected to flow through the wire (which I could figure out)?

Is there a formula for finding the temperature of a wire? If I know how many volts I put on a wire, the resistance of the wire per foot, the length of the wire, and the ambient air temperature. Is that enough information to determine what the wire's temperature will be? Do I need more...
