What is the electric potential difference? Electric potential: The electric potential is defined as the amount of work required to move a unit charge from a reference point to any specific point in the presence of an electric field. It is also defined as the electric potential energy per unit...
19.4 Equipotential Surfaces and Their Relation to the Electric Field A Capacitor: A common electric device with a constant E-Field inside. The plates of the capacitor are separated by a distance of 0.032 m, and the potential difference
The electric potential difference between two points in an electric field is defined as the change in potential energy as a result of movement of test charge between the two points, divided by the test charge. {eq}\Delta V = \displaystyle ...
This potential difference (p.d.) is the sum of several contributions: electrode contributions, a liquid-junction contribution—not membrane-dependent—and finally a contribution specific to the membrane system. The latter contains a diffusion term and an electric charge term. The charge term is ...
(General Physics) the difference in electric potential between two points in an electric field; the work that has to be done in transferring unit positive charge from one point to the other, measured in volts. Symbol:U,ΔVorΔφAbbreviation:pdCompareelectromotive force ...
electric potential differenceQuercus cerrisbioelectricityElectric potential differences (EPD) had been continuously recorded for four years from 1997 until 2001 between electrodes inserted in sixteen selected sites of the trunk of a turkey oak (Quercus cerris L.). In our earlier paper (Kopp谩n et al...
解析 A。“potential difference”电势差是驱动电流的力。选项 B“the rate of flow of electric charge”是电荷的流动速率;选项 C“the opposition to the flow of electric current”是对电流的阻碍;选项 D“the electrical energy stored in a conductor”是导体中储存的电能。
The maximum potential difference across the terminals is called the electromotive force (emf). The emf has units of Volts, e.g. a 12 V battery has an emf of 12 V 20.1 Electromotive Force and Current The electric current is the amount of charge per unit time that passes ...
Voltage Drop, Potential Difference and EMF To give the concept of voltage a well-defined meaning in time-dependent electromagnetism, we advocate that it be defined as the retarded electric scalar potential [1, 2, 3] in the Lorenz KT Mcdonald 被引量: 0发表: 2012年 potential difference 1. ...
1 英语翻译 eletric potential difference: the amount of work reuqired per unit charge to move a positive charge from one point charge to another in the presence of an electric field 这里的a positive charge做什么解? 中文应该是每单位电荷从A移动到B做的功,叫做AB两点之间的电势差 可是我怎么翻译不...
