Electric Resistance of Conductors & Semiconductors with Temp Change

[noor.lalu]

1.What happens to the electrical resistance of conductors, semiconductors, with increase in temperature? And explain why?

You could have googled.

For conductors, the resistance will increase with T, while for some semiconductors, the resistance may decrease with T, which results from the agitation of the electrons in the valence band

thank u soo much now i clearly understand
