1. The problem statement, all variables and given/known data Here's the question: http://puu.sh/171ls [Broken] 3. The attempt at a solution I have no idea where to begin. It says R(AB) = R(L) = 301 ohms. What does that mean? Does R(AB) mean the resistance from A to B? Is that the total resistance? The total resistance is equal to 301 ohms which is also equal to R(L)? I don't know. Any help would be appreciated.
