In the figure below, two points A and B are located within a region in which there is an electric field. The potential difference Δ V = V B V A is 1 2 3 33% 33% 33% 1 2 3 4 5 1. positive 2. negative 3. zero
When moving straight from A to B , E and d s in Equation 25.3 both point toward the right. Thus, the dot product E · d s is positive and Δ V is negative.

In this figure, a negative charge is placed at A and then moved to B . The change in potential energy of the charge–field system for this process is 1 2 3 33% 33% 33% 1 2 3 4 5 1. positive 2. negative 3. zero
From Equation 25.3, Δ U = q 0 Δ V , so if a negative test charge is moved through a negative potential difference, the potential energy is positive. Work must be done to move the charge in the direction opposite to the electric force on it.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
