Electric Potential Between Multiple Points

Click For Summary
The discussion revolves around calculating the electric potential difference between points 3 and 4 (V34) given the potential differences V12, V23, and V41. The key equation used is that the sum of potential differences around a closed loop equals zero, leading to the equation V12 + V23 + V41 + V34 = 0. Substituting the known values, V34 is determined to be -140V, indicating a negative potential difference. The participants emphasize the importance of understanding how to manipulate the equations to find the unknown potential difference. The conversation highlights the confusion surrounding the application of these principles in solving the problem.

What? That can't be right. And, if it is, WOW do I feel dumb!

A shortcut is to remember that the sum of all potential differences added around a closed loop is zero.
