Electromotive Force and Faraday's Law. Inductance, Energy in Magnetic Fields, Maxwell Equations. 电动势(EMF)及法拉第定律。电感,磁场中之能量,马克思威尔方程式。
The DC electromotive force output by AC generator can have quite big pulsating voltage. 交流发电机输出的直流电动势(EMF)会有较大的脉动电压。
The induced electromotive force and the current do not move along evenly together, that is, in phase. 感应电动势(EMF)和电流并不协调一致地变化,即并不同相位。
The electromotive force between the two poles of this battery is 3.6v. 这个电池两极的电动势(EMF)是3.6伏特。
Years in the motor current is outside the power supply from the induced electromotive force and the direction of armature current I in opposite directions. 在电动机里电流是由外电源供给的感生电动势(EMF)的方向和电枢电流I方向相反。
