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 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 前者是相对于0势能位置的势能，后者是指任意两个位置的势能差

n identical condenser are joined in parallel and are charged to potential V. Now they are separated and joined in series. Then the total energy and potential difference of the combination will be A Energy and potential difference remain same B Energy remains same the potential differnece is nV...
Potential difference is also known as voltage, electric potential difference, or electromotive force (usually with an implied difference or gradient). This measure also is the energy per unit charge that is required to move a charged particle from one point to another. In this way we represent ...
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...
To say we have a 12.0 V battery means that its terminals have a 12.0 V potential difference. When such a battery moves charge, it puts the charge through a potential difference of 12.0 V, and the charge is given a change in potential energy equal to ΔPE =qΔV. ...
