No. We cannot constrict our single registers. A cut from the G one. Good. We can just write the effective resistance for the circuits. For the resistance of the resistance is like 2.0 and a 4.0, which are in Siri's and for the resistors off the resistance is like 1.0 Amanda 5.0, which is also in cities. What we cannot, you know, reduced the second Father in part B of this question, we have to kill Clay. The currents I want I do. And it I three. In order to kill Claire, these grants let me apply. The cook offs will rule in the upper loop off the yuan circuit. 24 Walt minus into 2.0 in tow. I want minus 4.0 into. I want minus 3.0 in tow. I three equals to zero, so this equation can simplify. It is 24 worlds minus exports. Little. You know. I want minus 3.0 into our three calls to zero. Their schooling equating one. No, applying the several in outer loop. We can right 24 Walter minus into two points. You don't me do I want minus four point. Is you all made? I want minus 1.0. And so I do. Minus one minus 5.0 in tow. I do. Plus 12. Walt equals to zero. So this equation can be simply five days. Six points of old minus. I want minus two equals to zero. Soldier scolded equation too. Now, using the cost current rules we can right by three equals two. I want minus. I too were squalid, equating Hey, now sitting the world off. I three from this question in tow. Equation one, we will get 24 world minus 6.0. I want minus 3.0 into I want minus two equals to zero. So this can be simplified days 24 Walt minus into 9.0 in tow. I want plus three points. Roman. Try to peoples to zero. There's gonna be quite in three. No one to play a question to buy three and adding the authentic way in with Quentin. Number three, we can write 42 world minus 12 in tow. I want equals to zero. So this will give us the value for Ivan is I one equals two 3.5 from bad. No city in the world. You off by one into according to we will get 6.0 world minus into one point. You don't into 3.5 Compare minus I two equals to zero. So this will you watch the value for right? Wes? I do equals two 2.5. I'm bad. Now sit in the world off. I won and I to into equation air. We will get the ready for three years by three equals two, one point doing better. So end of the question.
