critical voltage

critical voltage

[′krid·ə·kəl ′vōl·tij]
(electronics)
The highest theoretical value of steady anode voltage, at a given steady magnetic flux density, at which electrons emitted from the cathode of a magnetron at zero velocity would fail to reach the anode. Also known as cutoff voltage.

The model of the processes leading to breakdown of the dielectric presupposed discharge in the bubble when the critical voltage reached on it, the deformation of the bubble by Coulomb forces, the field amplification in the region of the poles of the bubble, and the discharge into the liquid after reaching the critical field strength.
The results also showed that charge does not only build up during walking; critical voltage levels can be reached simply by standing up from a non-ESD-certified chair or by removing and dropping a sweater.
In the present study, the critical voltage required to initiate nanofibres on the needle electrospinning system was lower than on the roller system.
A sudden collapse of the moving part can be observed at critical voltage (pull-in) of the microswitch achieving its ON or OFF state.
G-sensor to detect shock, thermal sensors to detect and manage heat, voltage sensors to control current and critical voltage sensors to protect key components.
The voltage output from the voltage converter is adjusted in such a way that the supply voltage drops below the critical voltage threshold even under worst-case conditions.
This dramatically reduced the critical voltage value needed to form spinning cones.
At some critical voltage, this force becomes greater than the surface tension, and a thin jet from the cone heads toward the negatively charged plate.
The surface mount resistor is suited for use in critical voltage divider applications where precision and stability are required.
Taking into account that for the tires 110 kV critical voltage can reach values of the order 0.8[U.sub.nom] [2], the use of reactive power change as a criterion must be confirmed by additional research.
Furthermore, a process diagram showing the relationship between the flow rate and critical voltage ([V.sub.c]) needed to fabricate nanofibers was measured.
