I know that the sum of the currents entering is the same as leaving. Also that the sum of potential differences is 0. I'm just not sure where to start with three batteries, plus one that is oriented different than the other two. Some of the videos that I saw on this topic had only 1 battery.
Hi, I'm new here. I've seen that other people have gotten homework help before. For this problem, I have to fine the current, in amperes, across the R, 80, 20, and 70 resistor. The R resistor is 236.6 ohms. I'm not sure where to start because of the three batteries. Here is a picture of my...
