In this question the electric circuit is shown and the resistance is given as 2 ohm.
00:10
So from the diagram we can see that these last three resistances are in series.
00:19
So the equivalent resistance will be r plus r plus r.
00:26
So on substituting value we get 2 plus 2 plus 2 or this will be 6 ohm.
00:33
Now on simplifying circuit we get this will be r equivalent and these are the remaining resistances.
00:47
So this will be r, r, r and r and these points are ab.
00:52
Now we can see that these are and these are equivalent in parallel.
00:56
So next r equivalent will be r multiplied by r equivalent divided by r plus r equivalent.
01:06
So this will be 2 plus 6 divided 2 multiplied by 6 divided by 2 plus 6.
01:12
So r equivalent one comes out as 1 .5.
01:17
Now we again simplify this circuit we get this will be points a and b.
01:24
This will be resistance r, this again resistance r...
