Now for this question, we want to find the current I one i two a night tree decided, treated from unknowns from the previous question circuit. So we got refer to the circuit in question E to now we have the look brew from the first, any top in the anti clockwise manner. We also have the junction equation that it's I tree es equals two. I want plus I to. So we have because we have tree unknowns. You need one more equation or more. Look, Equation. And one of the possible groups would be de external loop our charity bottom below our first look. So we're here. I gotta usti rich occur in the cook twice manner. It just got wise because you want to follow the current direction. So it's slightly easier for us to write down t equation. So we go to go twice manner starting from point A. So from point A b plus e to maybe battery you two from minus tow us. So yet? Yeah. Myth bypassed the internal resistance. The same dr is the current. So we subtract a really potential drop. You passed our tool, External resistance, same direction. It's current next we Pappas uh, awful for in the same direction ISTEA current The current ever looking at will be I tree since I tree is flowing at the bottom half 40 circuit so I tree ah for they re bypass Ah ah ah Battery You fall from plus to minus So this is in the opposite direction So we have to subtract way you fall by pastilles internal resistance off the other battery which are tree in the same direction current My feet are tree the bypass t Petrie from minus to plus So we Eddie Yeah, you treat Finally we have the last resistor which is our tree Same direction is the current sore subject Triage Greatest 20 Now we want to do is to simplify d e questions a little looping Audie Yeah, miss once Like there we group those terms with I two together and you group the terms if I treated better between the same thing with our first equation it is underlined over here simply fighting's a bit tu minus one group everything with I to and go everything we've I want Now you have three different equations. Triana Jones, you go. We will be able to soft for them. One of the Met it Ah, that's I'm going to use. Yes, I'm gonna substitute. I won. Yes, I want it close to I tree minus I to into equation to there we will be able to gets an expression off I to in terms off just a tree substitute and into equation. This secretion was surely rate one to finally, uh, soft for a treat. So let me just simplify everything a bit by putting into you numbers, not the substituting, the very step we have on the circuit figure we should be able simply file two equations into as such No me after your third equation, which is actually close to I want plus I to you know, that I want because to actually minus I two gonna substitute into equation too. Oh, we simplify this equation again and we re arrange to find what is I to from here? Why you have to do left substitute hidden I to to dis equation in question one to get our expression in terms off a tree. So there's the expression you will get after simplifying. Have you have you would get Ah, I tree from here to piece your points, you tree tree night, Fife. Yes, Jay's approximately. Is your point of your tree? Four MPs? No, I can't find I to By using substituting I tree into this equation. Everyone gets your point tree 788 Impious. Just approximately is your point tree. Eight MPs. Finally I won. I want iss close to I tree miners I to and we actually get a negative value. Just what is your point tree for five MPs? And this means that our initial assumption off the current direction off I won this room. So you see in the opposite direction in this but the magnitude off current.
