Hello students, to find the equivalent circuit you have to first read all the circuit.
00:08
So, you can see we have delta here.
00:31
So, we have a delta network here.
00:37
This is 50 ohm, this is also 50 and this is 100 ohm.
00:54
Then we have two 25 ohm resistance 25, 25 and then we have another delta.
01:08
So, this is 100, this is 50 and this is also 50.
01:33
This is the point a and this is the point b.
01:40
So, now we can convert the delta to star network.
01:46
So, by converting it into star we will have the circuit here we have r1, r2 and we have r3 here and these two can be combined as 50 ohm.
02:12
Then we have another delta which we can convert into star.
02:20
So, let us name this as r4, r5, r6.
02:40
This is a and this is.
02:46
So, now r1 is 50 into 100 divided by 50 plus 50 plus 100 which is equals to 25 and r2 we can similarly calculate r2 50 into 50 divided by 200 which is 25 by and r3 is again 25...
