Now here in this question, you're giving, you asking you to calculate the current density.
00:06
So basically it's current density.
00:13
The situation, let me just copy the diagram from the question for your convenience.
00:19
So it's something like this.
00:21
So this is the diagram.
00:24
What's happening is that, as you can see from this diagram, that let me see, so what's happening is that you have a current, right, your path current to this copper wire, right? this copper wire is supposed to have a radius all right.
00:43
So for example, this is a radius arrow and the wall has a thickness, which is d, right? the wall has thickness d and also the top plate of the thickness of top plate is also d right and this is much smaller than all.
00:58
So you ask what is current density in the tube, g1, and g1, and g as well.
01:03
So the g is a red current, and g1 is, of course, non -utadent current...
