when the distances are connected In Siri's, the resistance is simply add up. So we have a general distress off value to 75 each. Then the natural distance is 10 times the resistance. Because there are 10 resistance is that that will be 2750 or in part B, we can simply use the resistance for parallel configuration, which is net resistance is given by one over R one plus one over r two. I'm sorry about that. Just one divided by two up to one plus our tent because we have general distances. No, all of them have the same values. So this will be turned about it. Bye. 2 75 So if you'd taken in worse off it. Our end is 27 2 75 divided by 10 which is equal to 27.5. So you can see that in serious resistance is 10 times on in total resistance is decreased by 10 times
