    Voltage Point Problem.

    Greetings. I’m working on a example on finding the voltages between the various points. Now if you look at figure 2.13 A) & B) I need to find the voltages between points A & C in both figure examples. Now in Fig.A) the voltages between A & C is zero, but in FigB) the voltage point is 3. Now in...
