potential differrence就是初中物理里的电压，potential energy在引力场叫重力势能，一般喜欢用公式mgh表达，但是在电场就叫电势能，也有公式的。总之势能是与物体位置相关的能量。本质原因是力做功导致的
求问各位博士大佬,电..求问各位博士大佬,电势差(potential difference)=voltage和能量(energy)的关系. 萌新不懂 随便镇楼没人吗?

potential difference The energy difference that tends to make an electric charge or current move. It is measured in volts. Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual Information Limited ThesaurusAntonymsRelated WordsSynonymsLegend: ...
Although heat and thermal energy are related, there is a difference between the two. Heat describes the transfer of thermal energy in a system, while thermal energy actually measures the state of this heat energy in a system. Thermal energy also deals with properties of heat transfer like condu...
: the difference in electrical potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other compare action potential, generator potential, membrane potential, resting potential More...
The potential difference between two points says A and B, is a measure of the energy used by one coulomb in moving from A to B. Thus if the potential difference between points A and B is 2 volts, it means that each coulomb will give up the energy of 2 joules in moving from A to...
