Hi guys, now in this volume we are given to us the circuit.
00:03
What we need to find out in this volume? we need to find out the current which is flowing from the rc register.
00:10
This is r of a is what, 1 om, r of b is equal to 4 ome, this is 4 om, r of c is equal to 8 om, r of d is equal to this is 3 o, and r of e is equal to 5 om, and r of f is equal to 9.
00:35
0 .75 om.
00:39
Now what we need to find out in this column, we need to find out the current in the input rc.
00:45
So let's say the current is flowing like this.
00:50
Now from this position what will be happened, the current will be divided into two, three parts like this.
00:59
And if you see very carefully what you realize that this rd and re is in series form.
01:06
This is rd and re in series form.
01:12
From this series combination, this rc are connected in what parallel form? this rc are connected in parallel form.
01:22
So i'm going to write down this equation like this.
01:27
This is what we have another.
01:31
This is r of f.
01:33
This is r of a.
01:35
This is r of b.
01:37
So this is r of a.
01:40
This is r of b.
01:43
This is r of f and this will be what? this will be r of c parallel to r of d plus r of e.
01:59
And this will be better here.
02:03
1 .5.
02:06
Now this is 3 plus 5 which is 8...
