Generalized static volt-ampere characteristics of thermoresistors

Journal of Engineering Physics, 1977
Similarity criteria are obtained for static volt-ampere characteristics of thermoresistors and for thermoresistors included in a circuit. A technique is described for a simplified graphic-analytical design of a circuit with a thermoresistor and rules are given for modeling thermoresistors where the dissipation coefficient varies.

Volt-ampere characteristic of NbTi-wire with inhomogeneous filaments

Superconductor Science and Technology, 1992
The nature of the current voltage characteristic of NbTi-wires with inhomogeneous filaments was investigated on the wires with finite length filaments and filaments partially damaged by intermetallic particles created on the filament-matrix boundary.

Electrogradient EMF and volt-ampere characteristics of inhomogeneous systems

Soviet Physics Journal, 1978
This paper studies the manifestation of electrogradient effects in the shape of the voltampere characteristics (VAC) of inhomogeneous conducting sandwich structures of the SSS and MSM types (S stands for n-type semiconductor, and M for metal) during the passage of a current perpendicular to the interfaces between the materials.

Equation for terminal volt-ampere characteristics of MOS-controlled thyristors

Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 2003
An equation for the i/sub K/- nu /sub AK/ static characteristic of an MOS-controlled thyristor (MCT) is derived using a four-transistor equivalent model of the device. The equation is similar to that for forward-biased diodes. The equivalent saturation current of the MCT is a function of both the saturation currents and the forward and reverse current ...

On The Volt-Ampere Characteristics of Molecular Monoelectronic Elements

1989
The development of monoelectronic circuitry1,2 suggests that molecular materials could replace traditional materials and production means. That should allow circuit elements as small as a molecule (10 A) to be made.

Asymmetry of Volt-Ampere characteristics in poled polycrystalline Ferroelectrics-Semiconductors

Ferroelectrics, 1995
In poled polycrystalline ferroelectrics-semiconductors with intergranular potential barriers the voltampere characteristics are found out to be asymmetric, the current density along the polarization direction being smaller than that in the opposite direction. The degree of asymmetry increases with measuring field.

Research of volt-ampere characteristics testing method for photovoltaic cells

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
Volt-ampere characteristic(I-V) curve is one of the most important characteristics of solar arrays, and is an indispensable reference for field performance testing and designing of concentrating photovoltaic power generation system. However, customers can only get the curve under standard condition from manufacturers, but the actual operating ...

Electrical breakdown and volt-ampere characteristics in water vapor in microgaps

EPL (Europhysics Letters), 2012
Although the physics for breakdown initiation in gases in generally well understood, the process of breakdown initiation in liquids is much less clear. A large number of experimental data on the breakdown in water revealed that the breakdown voltage in water is of the same magnitude as in the case of gases.
