Problem 55 Hard Difficulty

The circuit in Figure $P 18.55$ has been connected for several seconds. Find the current (a) in the $4.00-\mathrm{V}$ battery, (b) in the $3.00-\Omega$ resistor, (c) in the $8.00-\mathrm{V}$ battery, and (d) in the $3.00-\mathrm{V}$ battery. (e) Find the charge on the capacitor.

Answer

a. I=56 / 55 \approx 1.02 \mathrm{A} \text { (anvent through } 4 \mathrm{v} \text { buttery })
b. \begin{array}{r}{4-5(1.02)=-0.363 \mathrm{A}} \\ {\text { (downward })} \\ {\text { direction }}\end{array}
c. 1.383 \mathrm{A}
d. I=0
e. \text { or } Q=(11 v)(6 \mu f)=66 \mu \mathrm{c}

Video Transcript

In the first part of this question, we are going to kill Claire. The current passing through the 4.0 Waldo to battery, which we call I took it in order to solve this question. Let me write the names off the loot From left writers a new one Look to end look tree No applying the gauchos current world We can wait by three equals dough I want Plus I do. That's cool it equation now applying the controls One day you'll look tree we can right 4.0 Walt minus I 3 to 5.0 mega into minus I doing toe trip 100 mega. He falls to zero, their schooling equation one more applying the several in Luke to weaken right at 100 Walt minus. I went into 5.0 mega into minus. I do into 3.0 omega calls to zero while sitting Well, you off. I want from a question A into this equation, you can write 8.1 minus in tow. I three minus I do into five points. Is it omega minus? I, too. Into 3400 Medical's to zero. No simplifying this equipment we can, Right? Yet born 00 water minus I three into 5.0 My God. Plus I do into 8.0 mega. He goes to zero their school and equation, uh, two. Please know that there is. Plus, with this, I too here you have to write. Plus now multiply within one by it and equating to buy a tree and then adding the body questions we can, right? 56 points It award to minus into 55 points in omega into a tree close to zero. So this squares us devalue. For three years. I three calls to 1.0 wanted a pair, but it can't be. The Internet by three equals two 1.2 I'm bad. In part b of this question, we have to kill Claire, the current in 3.0 omega resistor. But it is I do, in order to calculate, decide to We put the value off tree into a quiet one 4.0 Walt minus into 1.1 Adam pad into 5.0 omega minus two into 3.0 matter equals to zero. So, stalling this equation for I do, we will get I do equals two 0.363 in party off this question, we're going to kill Claire. The current passing through airport 00 What battery? Which is I want now setting the wedding's off I two and I three into equating a we can, right. I want people to one point. You wanna get a bad minus 0.363 bed, which is it goes toe. I want equals to one point create in bed. So this will be plus as a we have a negative sign with two. So the negative negative, the multiplication off the great, different negative. You know, we'll give you a plus sign so you can see there should be a negative sign. We die to which we have missed in body. We have to kill Claire. The current passing through the 3.0 volt battery. That is. So we do that when the capacitor is charged. Completely charged them There will be looking and along the survey three because they're off the separation of the plates off the capacitor. So we can light I equals to zero in bed. In party off this question, we have to kill cleared up charges on the CA Bextra. But it is in order to kill Claire. This cure let me find the potential difference across the capacitor through the cultures will rule we see was to wear 0.0 Walter plus 3.0 which is close to we see close to 11 points your world. No, the capacity requested it. Can we close toe? See, we see now sitting The wedding's off this year and we see into this quiet we will get two equals to 6.1 Claritin is for money. Six fair art into 11.0 vote. So this will give us 66.0 Micro column. So end of the question
