Exempel på electromotive

• A voltage may represent either a source of energy (electromotive force), or lost, used, or stored energy (potential drop).

• An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the original change in magnetic flux.

• The motion is azimuthal and the field is axial, so the electromotive force is radial.

• Electrochemical cell voltage is also referred to as electromotive force or emf.

• When a permanent magnet is moved relative to a conductor, or vice versa, an electromotive force is created.

• He proceeds to test them with a multimeterand by a fateful error, sets the multimeter to measure resistance rather than electromotive potential (voltage).

• When alternating current is supplied to the field (stator) winding, it induces an electromotive force (emf) in the armature.

• The electromotive force generated by motion is often referred to as "motional emf".

• 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.

• 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.

• 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).

• Besides the electromotive force, magnetic forces also cause a coupling between the magnetic and the mechanical field.

• The concentration of the chloride determines the absolute potential; the electromotive forces however are also dependant upon temperature.

• We shall introduce now the notation so-called electromotive force.

• When this happens, the potential difference (p.d.) across the capacitor is equal to the electromotive force (e.m.f.) of the supply.
