Hi,(adsbygoogle = window.adsbygoogle || []).push({});

my question is say you have a heat mat 11" by 11" one that is 7W and the other is 12W, will the 12W heat mat produce more heat and how do you prove this by means of mathematics?

Further to that, say if you have 6"x11" that is 10W and then a 11"x11" that is 20 watts, would the second one produce more heat or less or similar (minute diff), as it has a wider area to heat up?

This is with regards to UK input 3 pin plug system.
