The membrane capacitance (C) is a function of the stored charge divided by the potential difference across the membrane. As a result, any potential difference change generates a capacitance transient. Membrane capacitance is directly proportional to surface area, so biophysicists often use membrane ...
The capacitance of an arbitrarily shaped object is calculated with the same second-kind integral equation method used for computing static and dynamic polarizabilities. The capacitance is simply the dielectric permittivity multiplied by the area of the object and divided by the squared norm of the Neu...

The capacitance of a component can be varied at will by adjusting the mutual surface area between the plates, or by changing the spacing between the plates. The two most common types of variable capacitors (besides varactors) are the air variable and the trimmer. You will also sometimes encoun...

It is defined as capacitance per unit mass, per unit area, or, per unit volume, and corresponding specific capacitance is known as gravimetric capacitance (F/g) or areal capacitance (F/cm2) or volumetric capacitance (F/cm3) respectively. Now capacitance is given by charge divided by volt C...
A capacitor can be made variable rather than fixed in value by varying any of the physical factors determining capacitance. One relatively easy factor to vary in capacitor construction is that of plate area, or more properly, the amount of plate overlap. ...
The capacitance of a parallel plate capacitor is given byC=εrA/d. The energy stored in a capacitor is calculated by the work done in moving charge onto the plates.dW = V dq. The energy store is the area under the charge/voltage plot. 1/2QV or from C=Q/V, 1/2CV2= 2Q2/C....
the capacitance multiplier also includes a capacitor C1and a multiplying section30. The active load10is self-biasing because the active load10generates a bias voltage without using a separate bias current, for a reduced area and higher stability. A first node is an I/O (input-output) terminal...
