Hi, in the given problem, this is the circuit diagram whose equivalent resistance we have to find.
00:12
First of all, in the uppermost branch, there are three identical resistors, each having a value of 100 oom in series.
00:26
Then in the middle branch there are only two resistors in series again and having the same value of 100 oom.
00:41
Finally, there is a single resistance in the third branch and this one is also having a value of 100 oom.
00:51
Now we have to find the equivalent resistance between the terminals a and b.
00:59
Are equivalent.
01:01
So first of all, these three resistors are in series, then these two are in series.
01:09
So r1 means the equivalent resistance of the uppermost branch is equal to 100 plus 100 plus 100 o.
01:24
Or this is 300 o.
01:27
Then the equivalent resistance of the middle branch that is also in series.
01:34
So this is 100 plus 100 om or we can say this is 200 om...
