this question says that they are a mask you're into running through a secret is off 0.15 and peers and such circle. It has 150 homes off resistance. In the first item off the question, we have to calculate what is the average power consumers by such circuit. So So we have to use the following relation. I believe he is equals to our times. I r M s squared and now we have to do now is plaguing the given values in this equation to get our first answer. So 150 times zero point 15 squared and these easy goes to three point 3 75 What off consumer power. In the second item, we have to calculate the maximum power consumers by that circuit. So the maximum power it's too close to and times the maximum current squared. And now we have to complete what is the maximum current? So remember that we have this relation between the Ari mask. You're it onda maximum current. So the ari masking her it is the question the maximum clearance divided by the square root of two. Then the maximum could rent is it close to They are a mass current times the square root of two. So the maximum power consumers by the circuit is equal to are times two things I R and s squared and leaders equals two, 150 times two times 0.15 square. Which easy course, too. Six 0.75. What?
