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.

leakage current

In electrosurgery current that flows toward a ground along a path that the surgeon did not intend.

In this section power dissipation, leakage current and delay analysis is performed at circuit level for 0.
Table-I-V demonstrates the power, leakage current and delay for supply voltage scaling in 0.
The importance of reducing leakage currents has grown tremendously with the development of devices manufactured using 65nm-and-below features.
To be successful, and thus lead the capability of fabricating chips with sub-65nm technologies, leakage-reducing counter-measures must be rooted in the design domain, as continuous process improvements are not expected to be sufficient to cope with the increased leakage currents in next-generation semiconductor devices.
This is said to be invaluable to high voltage applications because without it, contaminants on the surface of the insulators become wet and produce a conductive layer, which is said to contribute to an increase in leakage currents, dryband arcing and ultimately flashover.
In this case, the fixture leakage currents are lower than the sample currents by a factor of 1,000, causing less than 0.
Jim Oakes commented further on ParaScan: "By adding dopants to BST, ParaScan reduces leakage currents by more than an order of magnitude and significantly decreases the RF losses in the material.
Along with Q values as high as 150 at 1 GHz and 80 at 2 GHz the integrated capacitor circuits demonstrate leakage currents of less than 100 nA and greatly improved reliability.
