Hello, in this question we are given two bars.
00:02
Each of the bar has a resistance of r.
00:06
This is first bar having a resistance r.
00:08
And this is second bar having a resistance r.
00:12
Alright, in first case, it is being said that they are connected by ends.
00:17
This hand is connected to this hand.
00:19
That means, it is a series combination.
00:22
This is r resistance.
00:23
This is r resistance.
00:25
And the r equivalent for series combination is what? summation r i and what is this what does this means it means that some of all the resistance that are connected in the series so r1 plus r this is the answer and in the other case in the case b it is being said that they are welded by side they are connected by the side like this right this is r this is r this is similar to the combination of parallel combination like this.
00:58
All right.
00:58
So here it would be rrr...
