Electric Potential Video Lessons

Concept

Problem: In the diagram below, there are two charges of +q and - q and six points (a through f) at various distances from the two charges (figure 1) You will be asked to rank changes in the electric potential along paths between pairs of points. Using the diagram, rank each of the given paths on the basis of the change in electric potential. Rank the largest-magnitude positive change (increase in electric potential) as largest and the largest-magnitude negative change (decrease in electric potential) as smallest. Rank from largest to smallest. To rank items as equivalent, overlap them

The change in potential:

$\overline{){\mathbf{∆}}{\mathbf{V}}{\mathbf{=}}{{\mathbf{V}}}_{{\mathbf{f}}}{\mathbf{-}}{{\mathbf{V}}}_{{\mathbf{0}}}}$

V = kq/r

In terms of kq/r

From f to e, ΔV = - 4/5 - (-1/3) = - 7/15 = - 0.467

From c to b, ΔV = 4/5 - 0 = 0.8
