the answer of the party off this question is that no, we cannot reduce the circuit in tow. A single and a sister, sir. Good. In part B of this question, we are going to kill Claire. The currents passing through each of the yuan resistors these grants are I want I do. And I three now let's apply the controls. Well. Did you rule in the upper loop off the human circuit? You won minus. I want I want blood I to our two minus two equals to zero. Now let's righty. Well is for this equation. 20.0 world minus 30 points. Dough I want plus 5.0 I do minus 10 borns. Your world calls to zero now simplifying this equation. We can, right? Two points. It was little world minus X point. Digital you do. I went plus 1.0 And so I do. He calls to zero their school. Antiquated one. No applying the symbol for water loop. We can, right? You want minus? I want. I want minus I three are three equals to zero. No, setting the values into this question will give us one de 10.0 world when a 30 points at all, you know, I won minus 20 points. You don't mean by three equals to zero. Let's call it equation to now using the kickoff current rules we can, right? I three equals two. I want plus I, too. Let's call it equation there now, setting the world off by three from equation Air into equation, too. We will get 20 points year old, minus 30 points in tow, one minus 20.0. Mean to I want Lassiter equals to zero. No, simply find this question. We can write 2.0 world minus 5.0 minto I want minus 2.0 Minto are two equals to zero. There scored equating free, no multiplying equation one by two And then adding your panic, Wayne. With equating number three, we will get she export zeros award minus 17 point judo in tow. I want equals to zero. So this will you have the early before I won is I want it calls too. 0.353 impair Now setting the value off this I want into equated to we will get two points little suitable to my next exports, it does it all into 0.353 and bear in tow plus 1.0 in tow. I two equals to zero. So this will. This will give us the well before I do. Has I do equals two 0.1 Won a bet. No sitting. Well, you off this? I too And I want into a question. Hey, we will get I three equals to zero point 353 impaired plus 0.118 impair. So this will give us the William for three years by three equals two 0.471 impact. So end of the question. Other Schools
