ΔV is most closely tied to energy, whereas E is most closely related to force. ΔVis a scalar quantity and has no direction, while E is a vector quantity, having both magnitude and direction. (Note that the magnitude of the electric field strength, a scalar quantity, is represented by E below.) The relationship between \(\Delta…

In equation form, the general relationship between voltage and electric field is E=−ΔVΔs, where Δs is the distance over which the change in potential, ΔV, takes place. The minus sign tells us that E points in the direction of decreasing potential.) The electric field is said to be the gradient (as in grade or slope)

The electric force then causes particle motion. In the case that the electric field is uniform, kinematics can be used to calculate the position and velocity of the charged particle.
