Web1 de set. de 2005 · The model characterizes transcellular impedance into three unknown solution parameters in confluent, cultured cells: Rb (the impedance due to cell-cell adhesion), α (impedance due to cell-matrix adhesion), and Cm (membrane capacitance due to transcellular electrical conduction).
Web24 de abr. de 2014 · The imaginary impedance as mentioned above, is the energy storage part. When a circuit element has a purely imaginary impedance, like, an inductor or a capacitor, in a harmonic AC circuit, the current through these elements is out of phase of the voltage across them by 90 degrees. In analog circuits a high impedance node is one that does not have any low impedance paths to any other nodes in the frequency range being considered. Since the terms low and high depend on context to some extent, it is possible in principle for some high impedance nodes to be described as low impedance in one context, and high impedance in another; so the node (perhaps a signal source or amplifier input) has relatively low currents for the voltages involved.
WebImpedance means alternating current resistance and, in contrast to ohmic resistance, takes into account that, e.g., capacitors become increasingly conductive with increasing frequency. Impedance spectroscopy uses the association of the capacitance with the …
