Homework Equations
/ 3. The Attempt at a SolutionLooking to solve mistakes to study from homework. Here's what I had so far[/B]
Aren't the currents going in the same direction, though? - They're both moving in a clock-wise direction?The batteries are arranged in opposite polarity. Check your second equation.
Sum of potential changes (gains and drops) should be zero.Because your overall voltage of the loop should end up =0?
Usually, you can't predict that. You should assume the directions of currents first and solve the KVL and KCL equations. If the current direction assumed is incorrect, you'll get a minus sign in the answer.If you start with 10V and on the opposite side is 5V, is it bc of Kirchhoff's voltage law that the voltage drop would be negative over the 2kOhm to 5V battery
