Electric potential is the work done to move a positive test charge from infinity to a given point within the field.
Just as gravitational potential energy is converted into kinetic energy for objects in free fall, so to is electric potential energy converted into kinetic energy for charges moving freely in an electric field. So if charge q traverses a potential gap V, then the magnitude of its change in p...
21-3 Electric potential & potential difference 物理学是整个自然科学和现代工程技术的基础。英文版大学物理课程的开设,首先是使学生掌握专业所必须的物理基础知识和专业词汇;进而要让学生对物理学的内容和方法、工作语言、概念和物理图像,其历史、现状和前沿等方面,
electric potential n (General Physics) a.the work required to transfer a unit positive electric charge from an infinite distance to a given point against an electric field b.the potential difference between the point and some other reference point. Symbol:VorφSometimes shortened to:potential ...
Potential Difference The potential difference between points A and B,VB–VA, is defined to be the change in potential energy of a chargeqmoved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. ...

Video: Electric Potential Watch the following Physics Concept Trailer to see how impressive new technologies are able to measure and utilize electric potentials.
Moving an electric charge from one location to another is not unlike moving any object from one location to another. The task requires work and it results in a change in energy. The Physics Classroom uses this idea to discuss the concept of electrical en
