from a given circuit. Then resistance two and three is equal. Thio too. Plus you are three which is ah to ease a one and our three&#x27;s a three. So these haired ups and coolant resistance off three home Um So then our one 123 becomes well. This will be in peril which is one over r one plus one over are 23 So it&#x27;s obstructing the values for our do tree from above and are one is six. This gives us are one tree. So here we have one over six plus one word three and then the resultant are 12 threes, 12 trees but to home. Sorry to him then. The coolant total equivalent resistance we have here He&#x27;s ah one do tree 123 plus are for four Where are wanted trees too, adding we did for here we gets the total equal and resistance off a six along. So Bardi is the right answer

so to get the equivalent resistance off this whole system first, we&#x27;ll try to figure out the shriveled resistance off this parallel connection. So let&#x27;s call it R P. So that&#x27;s equal to one over eight homes plus one over a domes, which is equal to two over eight homes. So are we is equal to four owns. So now four rooms and ah, storms are in serious connection. So we know that sees connection just add up. So the Maryland resistance in Siri&#x27;s is equal to four arms plus storms, which is six homes. So the final the Cuban Resistance is six homes, which is option D thanks.

so digital. Mind the current flowing through our tree to be equal to two ampere. Now again, we can use onslaught to find the world. It&#x27;s drop across on tree blooms. Losses that is equal to times are so we can find the world is dropped across Artie by using this equation. So we have to UN beer, which is the current going through the resistor on the value off the resistance. Just one. And this gives the world its drop to be Duval&#x27;s. So the correct answer is going to be option a.

Abhishek Jana · Answer

So if we simplify this circuit diagram, which is here Ah, we get something like this where the twelve homes and twenty two owns resistor are in Siri&#x27;s are in parallel and then four point five arms, for instance, in series with these two guys. And then this whole setup, isn&#x27;t it Panel connection with forty knows and ah, let&#x27;s let&#x27;s actually call this set up R one, two, um, so that it&#x27;s easier to calculate now. The first job for us is to find out this are one toe value, so it&#x27;s going to be our one two. It is equal toe, one over twelve homes, plus one over twenty two homes. Reciprocal of that, and that gives us seven point seven six five homes. Now, since this guy&#x27;s in serious connection with four point five, so the total on then let&#x27;s call this guy our three. So the total, um, the Cuban resistance will be our one two three, which is four point five plus seven point seven six five homes, which is equal to twelve point two six five homes. Okay, let&#x27;s actually needs some space here, right? So yeah. So now we know this on from there. We know that for genomes is in parallel connection with this whole set up. So that&#x27;s going to be R. Thank you. Well, it is parallel. So that&#x27;s going to be one point one over. One, two, six, five home. So that&#x27;s this guy plus one over fourteen Holmes, Reciprocal of that and bad gives us all right on. That gives us six point five three eight homes. Let me actually represented properly so that we can understand. So now this whole setup we call this are one, two, three, right? So that&#x27;s the equivalent resistance off the whole circuit For part B. We need to find the current that&#x27;s going to this resistor for genome. So what we can do is we can apply kid jumps, look rule on this slope, and if we do so, we see it&#x27;s going to be shy minus. I won four times are one for so I want for is basically the current that&#x27;s passing toe forty nine resistor. So if we solve for I won four, we get something like this. And here our yemma, folded or shy is given, so that that&#x27;s how we get our current. So now we know that point four two eight six m&#x27;s current is goingto this part. So we need to figure out what amount of current is going to home. We need to figure out what amount of current is going to our twelve. And our twenty two, um are twelve in prison. So what we do here is again we&#x27;re using culture of slaw loop rule for the outer loop and by out of love, we mean that we take this whole thing and we&#x27;re considering these two men sister as one. So that means instead ofthe writing these tow separately, we&#x27;re writing our one toe, so that means the current. So that means this guy and this whole thing is in serious connections of the current going too. The set up will be same. So that&#x27;s what we did here. So shy is positive because so we&#x27;re taking direction with his anti clockwise. So then you know the current passing tow the equivalent resistance, then the same kind is passing to four point five on register as well, and this total thing gives a zero. So from there we get our i wantto current the current that is passing tow This system And if we solve for it So we know the values we got those here on DA for one five is known. So if you plug in the numbers, we get power kind as point for eight, nine, two amps And from there we can solve for I want to on DA That&#x27;s gonna be okay. So before we start for I wantto we we should know that now this I wonders to current that is passing through with this guy is some ofthe eye that&#x27;s car passing to twelve resistor and the current response ing through this twenty two resister because they&#x27;re in peril connections or we add the current. So that&#x27;s what we did here. So and this is the hint forgetting I wantto or the kind of response ng tow twelve one resistor. Now what we&#x27;re doing here is first we&#x27;re trying to find out we&#x27;re trying to replace eye too. So that&#x27;s why you were writing. I do do in terms ofthe eye one dares to minus I wantto on. The reason we&#x27;re doing this is the four ring, so we know that the voltage across these two ends are equal because they&#x27;re in peril connection. So the voltage for twelve homes will be called to the voters for twenty two warms Ah, which is your present it here. And since this is the case we can use own slow and, um, certain says items are high times are equals, B. So that&#x27;s what we did. So this is the current for twelve on Minister, and there&#x27;s the current twenty two long resistor. So that&#x27;s that. And from there we can substitute I Toto in this expression and ah, we get something like this. So once we substitute this expression in this equation and then do some mathematical derivation we get I wantto as I wonder stood times are too divided by our one took us out to do. And we know all the values. We plug those numbers and that way we get different. That&#x27;s passing toe resistor. Okay, so let&#x27;s see, that was Park Si. Yeah, So for the final part, we know that two four point five resistor. I wonder as to amount of current is passing because this whole serve isn&#x27;t serious connection with that. So that means the same amount of current will be passing through both. So the current that&#x27;s passing to, um, four point five or Resister is equal toe. I wonders toe and we know that power is basically I squared times R So we can get I want to from here and our four point five is four point five. So you plug in the values we get. Four point point for eight nine who am squared times four point five homes. And that gives us the power is one point zero seven seven. What? Thank you.

select Start with finding the equivalent resistance off the circuit. So this sister are going on. Our two aren&#x27;t bad love. So the equivalent resistance off this particular combination that&#x27;s called that are one toe will be equal to Barton Arto over our one plus are too. So we have followed the reciprocal over here on DDE. If you substitute their values, that is odd. One is given to be six schools on our toe, his treatments and you get the icky violent resistance off the combination to be do it once. Now, this particular combination on our three are in cities. So the equivalent resistance off this combination that she will be, in fact the total violent resistance they equal toe on want to bless our tree because they&#x27;re connected in cities and our tree is content to be one home. So we substituted these two vandals. Over here on dhe, we get the total equivalent resistance to be treatments. So now that we have the total equivalent assistance, we can use homes law, that is V is equal. Do I r defined the total current. So the total current will be the thought of old age over the total equivalent resistance On the voltage off, the battery is given to be six bowls. The violent resistance is three owns, which gives the total current Toby to appeal. So this ISS the total contract Now since resistor Archie is in Siri&#x27;s with the Bagri. Therefore, the same current must flow through the resistor. Our tree therefore I three with the equal do too am beer as like so the correct answer is going to be option c. Thank you.

So in order to deter mined the power, we can use Ah, three formula so we can use power to be equal to current times. Voltage. We can use the square over our as another question to find the power when we can also use I squared times are on all these questions you can juggle between them by using The only solace is B is equal dough, i r. So that&#x27;s how you arrived at these questions. Basically, they mean the same thing. So here I am going to use the 1st 2 questions so betrayed and then be equal toe I three times the tree on these two values have already been found in problem 48 49. So current is from Toby to ampere and the voltage was formed to be two bulls. So the substitute that on find the power to be equal to four words to the correct answer is going to be option A thank you
