On Earth, the brightest auroras (the high - altitude glows often called the northern and southern lights) are generated when electrons in outer space near Earth are accelerated by large electrical potentials, or voltages, along the lines in our planet's magnetic field and slam into gas molecules in the upper atmosphere above polar regions.

Adding to our discussion of the many uses of the term «feedback» (24/31 December 2011), he says its purpose is to remind those working on the lines «that disconnecting a community's set of electrical appliances opens one to experiencing the full effects of collapsing fields» — that is, to voltages generated on the apparently disconnected wire when devices...

When the textile is then stretched or exposed to pressure, the deformation of the fibres causes a reorganisation of the charge distribution, thus generating an electrical voltage.

The piezoelectric effect allows a material to generate an electrical voltage when it is exposed to pressure or stretching.

When the antenna sends out a signal, information travels in the reverse direction, from electrical voltage to vibrations to EM waves.

Unlike conventional fingerprint visualization reagents, the polymers used by the University of Leicester researchers are electrochromic, that is to say they change from one colour to another when subjected to an electrical voltage.

The team used the key properties of zinc oxide, a material that when squashed or stretched creates a voltage by converting energy from motion into electrical energy, in the form of nanorods.

The open - sesame moment happens when a voltage is applied to a gate electrode, which increases electrical conductivity between two other electrodes, the «source» and the «drain.»

When high voltage current is applied to the electrodes, it excites the gases inside the bulb and forms an electrical arc between the electrodes

If there is no voltage present when the power lock switch is operated, the problem must be further traced using the electrical diagram.

The vent control valve (also known as vent valve or EVAP vent solenoid) and vent hose (on the left of the vent control valve in the diagram) need to be checked for blockage; The vent control valve also needs to be tested; the vent control valve is an electrical solenoid valve that closes when the voltage is applied.

The specially designed hybrid auto start - stop function ensures that comfort is not affected even when the vehicle is stopped in traffic for longer periods — because the automatic climate control and the on - board electrical system are powered by the lithium - ion high - voltage battery.

When the wind blows through them, it separates positive and negative charges as it moves the mist, which builds up to an almost 200,000 volt direct electric current that the system transmits through a high voltage cable back to the electrical grid on land.
