1. Homework Statement
We're learning about superposition in class right now and I'm having some trouble visualizing how to make simplifications using series/parallel connections. I attached the picture of the circuit and we're being asked to solve for the voltages and currents through the resistors.
2. Homework Equations
I understand the superposition idea, we have to replace each voltage source with a short and each current source with a open circuit. So for this particular example, I would first replace the 7V source with a short, then solve for all voltages/currents, then set the 28V source to a short then do the same, then algebraically add the results for the final answer. I'm having trouble doing this though.
For example, I first replace the 7V source with a short. I then have the 28V source, then the 3 resistors, would I be able to use the voltage divider rule to get the voltages through the 3 resistors, or should I use Kirchoff's laws? Please help and thanks in advance.
