I While current sources or sinks are abstract elements used for analysis, generally they have physical counterparts in real-world applications; e.g. A source or a sink is defined by which compartment is viewable by the observer. [3] The relationship is given by: where This page was last edited on 17 April 2020, at 09:31. The pink and green backgrounds are meant to symbolize different configurations, configuration 1 when charges are flowing in one direction and configuration 2 when they are flowing in the opposite direction.

Thus the cell would be termed a sink with respect to any flow of positive charges into it, and the cell would act as a source for any positive charges flowing out of it.

The relationship between the sum of the current sources and sinks and the voltage measured by the microelectrode probe may be calculated analytically if it is assumed that the quasi-static assumption holds, that the medium is spherically symmetric, homogeneous, isotropic, and infinite, and if the current source or sink is modeled as a point source. Current source density analysis[2] (which could more accurately be called current source and sink density analysis) is the practice of placing a microelectrode in proximity to a nerve or a nerve cell to detect current sourcing from, or sinking into, their plasma membranes.

Thus, by measuring a negativity relative to ground, the electrode indirectly reports the presence of a nearby current sink. Shown at right is a general two-compartment model to help illustrate the definition of current sources or sinks. In other cases, the model number may not be preceded by anything, but will be located in front of the sink dimension, such as 21 X 14. When positive charges, for example, flow quickly across a plasma membrane to the inside of a cell (sink) this creates a transient cloud of negativity in the vicinity of the sink. In electromagnetism, current sources and sinks are analysis formalisms which distinguish points, areas, or volumes through which electric current enters or exits a system. In this two-compartment model, the compartments are separated by a semi-conductive barrier (gray). The difference between the left and right panels is simply the location of the "eye".

There are three main types of kitchen sinks: drop-in sinks, undermount sinks and farmhouse sinks. Sink definition: A sink is a large fixed container in a kitchen, with taps to supply water. Using the same analogy, a current sink would be like water flowing down a drain - water travels from where it is observed to where it is not observed.

The size of the recorded negativity will vary directly with the size of the current sink and inversely with the distance between the electrode and the sink. Kitchen sinks come in different mounting styles and sink types.

This is because the flow of positive charges into the interior of the cell leaves behind uncompensated negative charges.
