电动势 Electromotive force

(重定向自Electromotance)
法拉第圆盘是同极发电机的原型。将铜圆盘旋转于固定不动的马蹄形磁铁,由于洛伦兹力的作用于铜圆盘的电子,会生成动生电动势。
格奥尔格·欧姆(1789年—1854年)
通常的反应途径会要求初始反应物越过一个能量障壁,进入中间态,最后出现于一个较低能量的状态。假若涉及到电荷分离,这能量差可能会造成电动势。更详细论述,请参阅条目过渡状态[10]。
使用KNO3玻璃管型盐桥的电化电池。

在电路学里,电动势英语:electromotive force,缩写为emf)表征一些电路组件供应电能的特性。这些电路组件称为「电动势源」。电化电池、太阳能电池、燃料电池、热电设备、发电机等等,都是电动势源。电动势源所供应的能量每单位电荷是其电动势。假设,电荷 Q\, 移动经过一个电动势源后,获得了能量 W\, ,则此组件的电动势定义为 \mathcal{E} =\frac{W}{Q} 。通常,这能量是分离正负电荷所做的功,由于这正负电荷被分离至组件的两端,会出现对应电场与电压差。

在电磁学里,电动势又分为两种:「感生电动势」与「动生电动势」。根据法拉第感应定律,处于含时磁场的闭电路,由于磁场随着时间而改变,会有感生电动势出现于闭电路。感生电动势等于电场沿着闭电路的路径积分。处于闭电路的带电粒子会感受到电场,因而产生电流。

Electromotive force 电动势

(重定向自Electromotance)
A typical reaction path requires the initial reactants to cross an energy barrier, enter an intermediate state and finally emerge in a lower energy configuration. If charge separation is involved, this energy difference can result in an emf. See Bergmann et al.[26] and Transition state.
Galvanic cell using a salt bridge
The equivalent circuit of a solar cell; parasitic resistances are ignored in the discussion of the text.
Solar cell voltage as a function of solar cell current delivered to a load for two light-induced currents IL; currents as a ratio with reverse saturation current I0. Compare with Fig. 1.4 in Nelson.[41]

Electromotive force, also called emf (denoted \mathcal{E} and measured in volt), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit. A device that supplies electrical energy is called a seat of electromotive force or emf. Emfs convert chemical, mechanical, and other forms of energy into electrical energy. The product of such a device is also known as emf.
