Questions: 1. What do you call the point inside the fault with dot mark? 2. How about the point above the dot mark below, what do you call it? 3. How will you differentiate the two points in the model?
The potential difference between two points ∆V is often called the voltage and is given by ∆V=VB—VA=∆PEq∆ V = V B - V A = ∆ PE q. The potential at an infinite distance is often taken to be zero
