When this happens, the potential difference (p.d.) across the capacitor is equal to the electromotive force (e.m.f.) of the supply.
We shall introduce now the notation so-called electromotive force.
The concentration of the chloride determines the absolute potential; the electromotive forces however are also dependant upon temperature.
Besides the electromotive force, magnetic forces also cause a coupling between the magnetic and the mechanical field.
A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals).
A high impedance voltmeter is used to measure the electromotive force or potential between the two electrodes when zero or no signicant current ows between them.
In the detailed analysis it was shown that the thermal fluctuations within the diode generate an electromotive force that cancels the voltage from rectified current fluctuations.
The electromotive force generated by motion is often referred to as "motional emf".
