Now here in this question, you are given two later questions.
00:02
Basically, some conceptual questions.
00:04
The first one is about the judamarder, right? judamalder.
00:11
And you're asked to explain the, to outline the basic assumptions of classical juda model, right? for electronic conduction.
00:26
Well, you know, judah model basically assumes that the electrons in a metal will just move according to the classical equation motion, right? the newton's equation, right? and i'm supposed to assume that this electrons experience kind of random collisions with the, with other entities such as lattice, labis, such as the electrons themselves, right? so that is the basic assumptions, right, in the electron, or of the, of the june matter.
00:59
And it has, i think it has, has a lot of successes when first jude proposed modern and applied to understand a lot of conduction phenomena and not just electric conduction, but i think semi -conduction.
01:16
But of course, there's a lot of values of the models where, for example, it does not, do not really take in account the fact that the electrons had to obey quantum statistics rather than the borthmandi statistics.
01:29
But i think it had a lot of successes.
01:33
And actually, it's used even today, the basic form of the judic model still used today, right? which says that the conductivity is kind of me squared thaw over a mass m.
01:44
Although now we understand the m is not just the electron, it's not just the simple electron density...
