Three 60.0-W, 120-V light- bulbs are connected across a 120-V power source, as shown in Figure P 18.50. Find (a) the total power delivered to the three bulbs and (b) the potential difference across each. Assume the resistance of each bulb is constant (even though, in reality, the resistance increases markedly with current).

a. P=40 W

b. V_{1}=79.2 V, V_{2}=40.8 V=V_{3}

c.$40 \mathrm{~V}$

here. In this case, the total wordage of night is off 1 21 And because of which the current flows through, our ribbons are torn artery. Where did you get a servant is, you know, great as B R. One were critical. Asarco we are to And where did Across our three as we are three. No, let's start. But step, eh? In ridge with you to find total power. Did he work to the tables? Write it down. Total power did you would two three bulbs. This is what we need to find out. So in this case, the first step would be We need to find her a distance off each book. You know across it. Bold though I right, bub, what age is equal to 60 word and both voyage is giving us one drink. It would, which is standard for all three off them. So therefore first music will do. As for the formula we square upon are there is resistance. So therefore, in order to calculate, are what we need to do. Isra Square two, divided by B In this case, value free is given as 1 20 So 1 20 world, the whole square one bow it is given a 60 worked. So answer that we get in this case is our is equal to do 40 homes. No, since all three light bulbs are having the same resistance. Since all three light bulbs are having those same resistance. Therefore, what we can see island is equal to our toe. Is it fair to our three? Easy, quick, too. That would be do 40 forms, which is again the value off our that we have. You know, it's fine. They go out under a distance first. So if you added resistance resistance off the combination Sebi our perfect you reading this notice therefore our effective is equal to are doing artery there in battle and their in cities with Armand. So what we can right here that are two barrel to our tree Yes, which is equal to do for Doom's battle to again the same letters to 40 homes less to 14 times Now to calculate the pattern combination that is multiplication off the two in the New America, an additional doing the denominator. So we go like that. So therefore But ultimately the value of our effective that we get is 1 20 plus 2 40 homes which is equal to 36 Humes, this is the are effective off the entire combination that we have every morning makes this We can write this Let to repower daily word Do the three boats be set building? Okay, that is the true power. So therefore beedies equal do seeing formula we squared upon all remember here it will be our effective because it is with respect to entire soaping so which is equal to 1 20 world square and the value off our effective is 36 umes to therefore don't recover. The word to the two bulbs is off 40 works. This is the main sponsor for the step Hey, that we have caught. No, let's start with this step. Be this right here. We need to find a potential difference across each bull. So just right now what we need to find is what are insured. Your friends. It's gross. Each book that is the value of cordage. So for this, we need to first find the dural current. So, in order to find a recurrent, we mention total current is equal to We can simply use the arms lawyer that his music will do. I endure So in order to calculate the value if I attribute racially and are to be upon aren't effective So and your fee that is applied working which is for 20 world and are effectively lose to these extremes. So therefore it is coming a zero born 33 amperes therefore to recurrent in this case will be off 0.3 t en years. Now the next ship Now let the potential difference across our one B. We are one that we already mentioned. So step See, we'll try to calculate the potential difference across our way. So the odd one is equal to I might be applied by Arwa using home so well you have eye we have zero born Tweety amperes might get played by are one is off do for fumes which is coming as argument Lee, 80 words a divorce. Therefore, let's try to understand this now. Now we are one. I write it here Iggy was okay and 1 20 will be supplied So 1 20 minus e t that will be off 40 words will be majored across. I drew on Artie. So just for your information I'm writing here 40 right now 40 bulls and 40 world as well Make we need to write the explanation for that. So I'm right here that Oh golf one Drink a void Night 80 walls What would be the potential difference? And gross I want that you already know to this 1 20 minus 80 which is equal to four cables. What he was maybe majored Gross I do and resistance are three shays They are connected in battle in. Therefore we can write the final answer as we are to and we are three is equal to 40 words This is what we regard as the second answer.
