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,
Now we can move on to the electric potential difference, or voltage. By definition, the electric potential difference, or voltage, is the difference in electric potential between the final and the initial position when work is done upon a charge to change its potential energy. Example for Ele...

Determine electric potential energy given potential difference and amount of charge. Figure 1. A charge accelerated by an electric field is analogous to a mass going down a hill. In both cases potential energy is converted to another form. Work is done by a force, but since this force is ...

Electric potential difference (also known as voltage) is a measure of electron pressure. It depends upon how tightly the electrons are packed and can be thought of as a measure of "how badly the electrons want to move" due to their mutual repulsion.What...
