In this problem, the Cuban do days wheeze equal to Drew for rewards, which is a sea war dish which is also known as our emissary of the wording. Because it'll mean square value, where a distance is giving us 0.25 forms and we need to calculate two parameters. One, this power dissipated. Already separated in this case is how much and they couldn't. So let's see Step, eh will calculate the power dissipated as average pole which is given their formula. We are a mess square upon the value of their distance. In this case, we are M iss is to 40 words who will get the square of that and are easily 0.2 firearms. My calculation. We get it, as do trees, you know, for definite zero, which we can the right he does to turkey point for killer warts. So in this case, the dissipated power in the short circuit will be off through 30.4 kill awards. No se step be, since we need to calculate the good so we can simply use whom the law in this case, which is really easy quarto I into our now value off mortgage is given us to 40 words. We need to calculate the value of I multiplied by. Are these off 0.25 homes? So we'll take simply that A show that is we are on our it is to 40 words divided by cedar 0.25 homes. By calculating this, we get the value s 9 60 amperes. So basically 9 60 amperes is the current which fluids to the short circuit And here is a second chance you
