All of student decision say find a notewan equivalent with respect to terminal a and b in the circuit shown.
00:08
So this is a circuit in which a one potential is applied 120 volt and there are three resistance 1 .40 on 12.
00:17
There are 2 points a and b.
00:19
We want to find equivalent and outland resistance and current or we can see equivalent notewan circuit for this one.
00:27
So first we find a norton resistance.
00:30
So for northern resistance, northern resistance, rn, first we remove all independent sources.
00:46
So suppose this is 20 -oom and now we remove this independent source.
00:54
So this is a 40 -oom resistance.
00:58
Now this is point a, one another resistance is 12 -oam is here and this is point b.
01:07
Now we remove this battery or we can say a sources of 120 old so here this is rn means northern resistance if they look at the circle we can say this 20 and 40 are in series so we can write like this at 20 series 20 and this series and this combination is in parallel with 12 o...
