1. The problem statement, all variables and given/known data For the network, calculate the voltage B to D [IMG=http://img13.imageshack.us/img13/1478/66772606.jpg][/PLAIN] 2. Relevant equations KVL, and Ohms law. 3. The attempt at a solution This is what i have: 45v-25v=Vt=20v Rt=4k+3K+2K=9k ohms From here on i am not sure what i am supposed to do.
