Electric Resistance of Conductors & Semiconductors with Temp Change

AI Thread Summary
The electrical resistance of conductors increases with temperature due to the increased agitation of atoms, which impedes electron flow. In contrast, for certain semiconductors, resistance can decrease with rising temperature as more charge carriers are generated from the valence band. This behavior is attributed to the thermal excitation of electrons, enhancing conductivity in semiconductors. Understanding these temperature-dependent characteristics is crucial for applications in electronics and materials science. Overall, the relationship between temperature and resistance varies significantly between conductors and semiconductors.

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

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
