1. The problem statement, all variables and given/known data The following is a link to the problem diagram and my work: http://imgur.com/a/9tppH [Broken] The goal is to determine the power through the 20V voltage source. 2. Relevant equations KCL and KVL: Currents entering a node sum to zero. Voltage drops around a loop sum to zero. 3. The attempt at a solution I tried to use mesh analysis as seen in the link above, but the answer I receive is incorrect. Its not in the images above, but the final power through the 20V voltage source would be P = IV or P = (1.66 A)(20V) = ~33.3 W, which is an incorrect answer. I appreciate any help.
