1. The problem statement, all variables and given/known data In a 50 V circuit with a 400 Ohm resistance and a 600 Ohm resistance in series; Point A is between the two resistors and point B is to the right of the 600 Ohm resistor. Charge is moving from right to left. 2. Relevant equations V=IR 3. The attempt at a solution The answer is supposed to be 30 V, but why isn't it 50 V?
