Suppose that a point charge of 1 Coulomb undergoes a change in which it is moved from point A to point B while in the presence of an external electric field. During this transposition, it undergoes a voltage change of . What change in electrical potential energy occurs in this scenario?
What is the electric potential between two terminals of a cell if it requires of work to transfer

electrons pass through a
resistor in 11 minutes. What is the potential difference across that resistor?
In a region of space, there is an electric field whose magnitude is pointing due North. An electron enters this field traveling due North with an initial velocity
. It enters the field at point A, where the electric potential is 1.5V. As it travels 2cm in the field to point B, the potential changes to 0V. What will the electron's velocity be when it arrives at point B?
There is an electric field of between two parallel plates of . The two plates are
apart.

A student is working on a laboratory exercise in which she measures the electric potential (voltage) at several points in an electric field. Before graphing the potential isolines, she measures the electric potential to be 3V at one point in the field and 7V at a point 3cm from the first point. What is the average electric field strength between the two points the student measured?
