current

 [kur´ent]
1. something that flows.
2. specifically, electricity transmitted through a circuit.
alternating current a current that periodically flows in opposite directions; its amplitude fluctuates as a sine wave.
convection current a current caused by movement by convection of warmer fluid into an area of cooler fluid.
direct current a current that flows in one direction only; when modeled as a wave, its amplitude is constant. When used medically it is called galvanic current. This current has distinct and important polarity and marked secondary chemical effects.
galvanic current a steady direct current.
current of injury an electric current that flows between injured myocardium and normal myocardium, because such cells have a reduced membrane potential; it may be either diastolic or systolic.
current of injury, diastolic the current that flows from injured to noninjured tissue during electrical diastole.
current of injury, systolic the current that flows from healthy tissue to injured tissue during electrical systole.
inwardly rectifying current current that rectifies so that it passes more easily towards the interior of a cell.
leakage current the electrical current that exists in the parts or metal case of electrical equipment.
outwardly rectifying current current that rectifies so that it passes more easily towards the exterior of a cell.
potassium rectifying c's transmembrane currents that rectify inwardly or outwardly to make adjustments in cellular functions; they are mainly responsible for the repolarization phase of the action potential. There are at least six mechanisms by which potassium ions move across cardiac cell membranes in the role of rectifier.

The total leakage current [i.sub.[summation][DELTA]](t) is a representative current --not the current in protective conductor, which is measured in practice.
Back gate biasing technique is more beneficial for NFinFETs due to their dominance in the total leakage current in FinFET based digital circuits.
The reduced leakage current of the process also creates a useful temperature margin with regard to the thermal runaway phenomenon.
Once the diode is in forward polarity, the SMU runs diode functional tests in the order stored in source memory, makes pass/fail determinations and saves data for each test--Forward Voltage Test, Breakdown Voltage Test and Leakage Current Test.
However, that thinness can cause larger gate leakage current. This is emerging as a critical issue, especially in low power products, such as mobile terminals, and it has spurred a search for thicker gate dielectric materials offering the same performance as SiO2.
It offers high speed switching and low-level off state leakage current of only 10 pA, with the rated load voltage (40V).
Besides, while high electron mobility is appreciated, III-V MOSFETs suffer from large drain leakage current when high electric field is applied [12-16].
For high-resistance samples, leakage current may degrade measurements.
Similar to the situation with leakage current in the diode tests, the zero-bias current improved slightly after a short while and remained stable over the rest of the test period--and at levels close to just 25 percent of the target value of 400 [micro]A.
The PMP92 series has a universal 90-264VAC input, choice of Class I or Class II AC inlets, single outputs from 12-24VDC, operation up to 5000m, low safety ground leakage current, 100% burn in, over voltage/short circuit/ overpower protection, no minimum load requirement, and an operating temperature of 0-60[degrees]C.
