• CAPACITORS
  • Modern capacitors are constructed using a range of manufacturing techniques and materials to provide the extraordinarily wide range of capacitance values used in electronics applications from femtofarads to farads, with maximum-voltage ratings ranging from a few volts to several kilovolts. (wikipedia.org)
  • thermal
  • A lumped capacitance model, also called lumped system analysis, reduces a thermal system to a number of discrete "lumps" and assumes that the temperature difference inside each lump is negligible. (wikipedia.org)
  • unavoidable
  • An aluminum plate having an aluminum purity of not less than 99.98% by mass and an Fe content of 5 to 50 ppm with the balance consisting of unavoidable impurities is used to realize increased capacitance of an aluminum electrolytic capacitor, reduced height, and improved high frequency characteristics.

  • change
  • In 1939 it was reported that " Nervous messages are invariably associated with an electrical change known as the action potential ," representing day-one of electrophysiology and the dawning of neural stimulation ( Hodgkin and Hukley, 1939 ). (frontiersin.org)
  • The shape, size and position of the fixed plate relative to the reed has an effect on the capacitance change as a function of the reed's instantaneous position during its travel. (wikipedia.org)
  • consists
  • The electrode geometry consists of two 4 x 4 parallel planes of copper conductors connected through custom built switch electronics to a commercially available capacitance to digital converter. (ucf.edu)
  • changes
  • The position of the fixed plate in the Pianet is such that the capacitance changes most dramatically when the reed is in the upper portion of its travel. (wikipedia.org)

  • varepsilon \nabla \varphi )=0} where φ {\displaystyle \varphi } denotes the electric potential distribution. (wikipedia.org)
  • The capacitance C {\displaystyle C} is a measure of electric energy W {\displaystyle W} stored in the medium, which can be quantified via the following relation: W = 1 2 ∫ ε E 2 d v = 1 2 C V 2 {\displaystyle W={\frac {1}{2}}\int _{}^{}\varepsilon E^{2}\,dv={\frac {1}{2}}CV^{2}} where E 2 {\displaystyle E^{2}} is the square magnitude of the electric field.

  • current
  • The increase in information-processing performance could be referred to in other words as an increase in processing electrical current at higher frequencies. (google.com)
  • This was because the electron energy levels in each metal shifted differently and a potential difference between the junctions created an electrical current and therefore a magnetic field around the wires. (wikipedia.org)
  • systems
  • Zengerle and Richter have shown in 1994 that micropumps could be modeled using the equivalence between fluidic systems and electrical networks [ 1 ]. (hindawi.com)
  • The technician is essentially performing a balancing act trying to watch and manipulate several systems simultaneously (motion, pressure, and electrical signals). (wikipedia.org)
  • method
  • Automated patch clamping is beginning to replace manual patch clamping as a method to measure the electrical activity of individual cells. (wikipedia.org)
  • effect
  • A sensitivity map was created illustrating the effect a clogged filter on the internal electric field of the filter. (sae.org)
  • interfaces
  • It is shown that a complete 2D map of the electrical properties of device structure, including delineation of regrown interfaces and the electrical nature of the regrown GaInP layer can be obtained. (diva-portal.org)
  • work
  • In this work, cross-sectional scanning capacitance microscopy (SCM) is used to investigate GaAs/AlGaAs buried heterostructure (BH) lasers regrown with semi-insulating GaInP:Fe. (diva-portal.org)
  • cells
  • In the case of cells in suspension, the pipette is completely replaced with a microchip with holes that can create gigaseals and measure the electrical activity. (wikipedia.org)
