  2. Capacitance - Wikipedia

    en.wikipedia.org/wiki/Capacitance

    Thus the system can be described by a collection of coefficients known as the elastance matrix or reciprocal capacitance matrix, which is defined as: =. From this, the mutual capacitance C m {\displaystyle C_{m}} between two objects can be defined [ 7 ] by solving for the total charge Q {\textstyle Q} and using C m = Q / V {\displaystyle C_{m ...

    Deriving the Woodbury matrix identity is easily done ... is known in numerical linear algebra and numerical partial differential equations as the capacitance matrix. ...

  4. Elastance - Wikipedia

    en.wikipedia.org/wiki/Elastance

    The definition of capacitance (C) is the charge (Q) stored per unit voltage (V).= Elastance (S) is the reciprocal of capacitance, thus, [1]= . Expressing the values of capacitors as elastance is not commonly done by practical electrical engineers, but can be convenient for capacitors in series since their total elastance is simply the sum of their individual elastances.

    en.wikipedia.org/wiki/Electrical_susceptance

    As a result, device admittance is frequency-dependent, and the simple electrostatic formula for capacitance, = , is not applicable. A more general definition of capacitance, encompassing electrostatic formula, is: [6]

  7. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Mutual capacitance allows multi-touch operation where multiple fingers, palms or styli can be accurately tracked at the same time. [13] Self-capacitance sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently. With self-capacitance, current senses the capacitive load of a finger on each ...

    The definition of capacitance, ... The first quantum dots were synthesized in a glass matrix by Alexei A. Onushchenko and Alexey Ekimov in 1981 at the Vavilov ...

  9. Permittivity - Wikipedia

    en.wikipedia.org/wiki/Permittivity

    The formula for capacitance in a parallel plate capacitor is written as C = ε A d {\displaystyle C=\varepsilon \ {\frac {A}{d}}} where A {\displaystyle A} is the area of one plate, d {\displaystyle d} is the distance between the plates, and ε {\displaystyle \varepsilon } is the permittivity of the medium between the two plates.
