in orderto find current to doom and the world it across it. First, we'll start with step individual. Apply Gabriel, that is, schedules work a shallow in the two different groups. So step one. Well, step a rather with a blank Ariel gave Ian steaks that are just bring some in a loop off mortgages is equal to zero. So in this case with it was you all right as humane Two parents, Ivan and I do moving clockwise in the two loops I showed in the so called dragon embryo. Now we'll apply. Came here to look one writing here applying okay, veal two you won with consider the current leaving the terminal across the compliment as they get you. So I already put up the direction off Iran this crack wise and the polarities which will be generated according to it. So when Ivan is more weak, polarity across four is plus to minus. But I digress to its plus to minus Israel. So now a right Dicky really question as minus troll minus four. Ivan minus two. They're the register value when deployed by Ivan minus. I do, because these are the two currents which are moving in the opposite direction, which is equal to zero number trying to solve this. That is minus tral minus for Iran, minus to Ivan. Plus, do I do is equal to zero. Finally, will get a question as minus six siren less to try to is equal to truck. And this is Adi. Question one. No, a blind kubo two You do will need to consider the current I do in disgrace and the direction according to you. So across the room now the polarities will be changed because I do is off first preference, sir. It'll be plus to minus and to six again. It is plus to minus. So applying will consider their living terminal polarity. So it will be minus it minus two into I do minus Ivan minus six. I do is equal to zero. Therefore, we try to solve this minus eat minus. Do I do? Blessed to Ireland minus six I do is equal to zero dead, for we get a question to us to liven. Minus you tied is equal to it. And this is our equation too. Now, when Solly question two in damn self in question one. So right here, solving immigration do in term self creation. One dead for true Ivan is equal to age. Bless it. I do. And therefore we'll get the value of five minutes full glass for I do it is considered this as a gration three. No, but this value in question one now. Therefore it will be minus six Ivan less Do I do musical patrol not putting the value of five and years that is minus six multiplied by full plus food. I do less Do I do is equal control. Therefore, by solving this, we get the Valium fight to us minus 36 on 22 which is minus 1.636 amperes. This is the value of fight with that big eight. Now put this one on you in immigration three to get the value of Ivan. So Ivan is equal to a full plus four. I do because equal to four plus four times minus 1.63 600 years. Therefore I won The final value that we get is minus two. Born 544 ampere. We need to consider the signer always. Now we need to get a value off current, which is going to do 10 4 I do. All that is going to groom is I to minus Ivan. You may even consider it as Ivan minus I do. But since we need to find the current from A to B, so I do is moving in the direction from A to B and Ivan these opposing do it. So there's reason he desired to minus Simon. Just put the value of Phi Tau as minus 1.636 minus sign it amazes seem and value of Ivan as minus 2.5 for four fine entities coming gas, zero point nine Zito, Age and beers, which we can write it at zero point 91 and beer. This is the value off current but is flowing through to whom and this is up for a sensor Now, since we need to can create the value of we'll get across two. So considering world age across to form register is we Abie. Therefore, baby is equal to simply using homes law that is I a b my deployed by its pedestal value, So value of I B B already ordered a 0.908 or humiliated at 0.91 multiplied by to register. So it is coming as 1.82 worlds. So therefore, value of the world it across to minister is 1.8 awards, and this is our second answer.
