I dropped the resistor into a pot of water and
placed the pot over a fire.
First try, resistor at room temperature :)
As I monitored the temperature, something weird happened. I was
not expecting this but the resistance started to drop, instead of increasing with increasing
First try, resistor dipped IN boiling hot water :)
This totally surprised me!
Because I was like what the heck is this? - is this negative resistance? -and that exist!
and that's a cool thing which I explain in another article.
So impressed and confused, I did some research and what I found was something very
interesting. Resistors are made of semi conductors!
Second try, resistor at ambient temperature :)
And semiconductors have a very weird
property. Due to increase in temperature, they become more conductive!
- And thats when I was like oh snap! After four dips and the same behaviour, I felt that I learnt
something today feeling! And here now is an
application of this weirdness, that enabled an electrical device to outperform its future

Very interesting... At high temperatures, semi conductors are better
