Work all circuit problems to two significant figures even if component values are given with one significant figure.Resistors $R_{1}$ and $R_{2}$ are in series, and the series combination is in parallel with $R_{3} .$ This parallel combination is connected across a battery. Draw a diagram of this circuit.

In this problem in the circuit, both of the switch are left unconnected. So here we can see that this switch is not connected to here or this which is not connected to here. So if we try to see a current path from, let us say walter source, we even then can't flows from here go to year and the circuit blocks at this position where is to is to be connected to point B. Similarly, if we go from battery, we too, the current will stop here at point A. Because it is not connected to switch as well, so we cannot complete a circuit in any way. If both the switch are left unconnected, this means that there will be no current flowing in the circuit and hence the current I uh the grand flowing through the sister are will be simply zero and Pierre. So the answer is zero. This completes the solution. Thank you.

High in the given problem. The two identical resistors are in parallel in the given circuit. Both of them are having the same resistance two or each. Then this parallel combination is joined in series with a third resistance having a value of for home and there is a battery having a voltage of 10 ball. First of all we will find the equivalent resistance of parallel combination. So this equivalent the resistance oh parallel combination of R one and R two Will be given by one by R. P. Is able to one by our one plus one by our two. I mean this is one by two plus one by two means this is two by two Which comes out to be one. Hence the value of parallel combination is one home. No this RP yes in series With the 3rd resistance are three. So equivalent resistance of the circuit will be given by R. P plus R. Three means this is one plus four on. It comes out to be five on So the current passing through the circuit and hence the same current will be passing through. This are three. Also because we know current remains same in series. So that current he's given by home slow as I is going to be by our I mean this is Stan Wall divided by five am, Which comes out to be two MPPS. So using these values, power dissipated in The 3rd resistance. R three Will be given by P is equal to I square in two or 3. So here this is the Squire off um pia Multiplied by our three, which was four on. And finally this power participated in the third resistor. Each second Will come out to be 16. What? Hence we can see here. Our option. See is correct. Thank you.

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.

Problem. 50 in this problem we have to calculate power dissipated through this resistor of resistance. We went on. So since we have to calculate power and so we need to know the two values. We know that the power is related in two ways that is V. Into I. R. Are you Squire odd or we Squire by our So either we know the value of potential and current through the resistor. We can calculate the power or we know the resistance of the resistor and the current through the resistor. Then also we can calculate power or if we know the value of potential and resistance of the resistor, then also we can calculate power In a problem. 48. We have already calculated that the current through the circuit and current passing through this register is two ampere and we know the value of resistance. So we can calculate the value of power using the relation Ari Squire are I? Was too. So this is two square multiplied by resistance is one. Um So this is equals two. For what? Since you need of the power is what? So from the given options option is the character option. That is for what? Yeah.
