So, in this portion here we have to find out the resistor that have a value 30 ohm.
00:08
Now if you see our the first portion then it is here a that is 20 ohm and this is 30 ohm.
00:25
Now this is 60 and this is here 10 ohm, 30 ohm, 60 ohm, 10 ohm.
00:40
Now here 40 ohm, this is 50 ohm, this is 50 ohm and first let write this 40 ohm, now this is 50 ohm, now here it will be 80 ohm, now this is 80 ohm, 80 ohm.
01:10
Now this is b, so we have to calculate this here, so if we calculate this let see here this is 10, this is 10, now it will continue r1 here and this will continue r3 and this continue with r2.
01:38
This is resistor first, resistor 3 and this is resistor second.
01:44
Now it will become the 40, now this will become 50 ohm and after joining this, so this is 50, this is 50 ohm and this is 40 ohm.
02:02
Now convert this delta into the star connection, so what we have to make a star connection and then we have to calculate r1 is equal to r12 which is multiplied by r13 and r12 which is added with r13 plus r23 that is equal to 10 multiplied by 40 and that is 10 plus 40 plus 50.
02:31
Now here r1 is equal to 4 here, now if we calculate r2, if we calculate r2 then we will get 20 ohm...
