Hi everyone,
Im new here, trying to teach myself about electronics using this website, "Practical electronics for Inventors", and what I remember from the physics classes I took back in college!
My question has to do with relative ground points on schematics and combining batteries. I have attached a crude drawing of part of the example from the book I am having trouble understanding.
I understand that points B and D are our reference, so our point voltage there is 0v. Point A has a voltage of 12V, and point C has a voltage of 9V. So, Vab=12V and Vcd=9V.
What I am having trouble grasping is what the process of finding the voltage from point A to C, or any other voltages where we have to find it across the two schematics. Could someone please enlighten me as to the process one would use in determining these voltages?
Thanks!
