Hello, in this question, so we have here 3 amperes in this direction, we have 2 ohms here, we have 8 ohms here, 4 ohms here, right, and we have 5 amperes, here we have 4 ohms, here we have 2 ohms, here we have 8 ohms and 12 volt battery, right.
00:45
So according to this, we can replace this 2 by 6 volt and 2 ohms resistance.
01:02
So here it would be v1, here it would be v2, v3 voltages, right.
01:08
So according to the nodal analysis at node v1, we would have minus 5 plus v1 by 4 plus v1 minus v2 by 8 plus v1 plus 6 v3 by 2 equals 0.
01:24
So at v2, it would be v2 minus v1 by 8 plus v2 by 2 plus v2 minus v3 by 4 equals 0.
01:36
And at v3, it is v3 minus 6 minus v1 by 2 plus v3 minus v2 by 4 plus v3 minus 12 by 8 equals 0, right.
01:53
So now, according to like solving all this from first, from v1, we have v1, 7 by 8 minus v2 by 8 minus v3 by 2 equals 2...
