Hi guys, now in this problem, the circuit is given to us and we need to find out r equivalent across point a and point b.
00:07
These two registers are connected in what parallel form? these two registers are connected in parallel form as well.
00:16
So the r equivalent of these two registers can be given as 12 times 6 which is what 12 times 6 divided 12 plus 6 which is what 18 and that is what this is 4.
00:31
Similarly, the r equivalent of this 4 and 8, that is at 4 times 8, divide by, this is 12, this gets cancelled 3 times, so we have 8 divide by 3.
00:45
That means r equivalent of this circuit is given as, let me draw the diagram again, this is something like that, this is a, this is b, this is 4, this is 5, and this 8 divide by 3.
01:04
So r equivalent will be what r of a b is equal to 4 plus 5 plus 8 divided by 3, 9 plus 8 divide 3.
01:14
So 27 plus 8 which is what this is 35 divided 3.
01:22
35 divided 3 is given as 11 .6 that is 11 .67 o.
01:32
This is what this is a r equivalent across point a and point p.
01:38
Now, the second condition is given to us, if i apply a battery point from a to b, this is something like that...
