capacitor is a device to store charge .it is based on the concept that when the potential of the capacitor is decreased it can gain some more charge so Q = CV where V is potential and Q is the charge stored then C is the capacitance. capacitance is the ability of the capacitor to store charge. expression for capacitance is C=ɛA/d where ɛis permittivity and A is area of capacitor plates ,d is plate separation.
Capacity or Capacitance of a capacitor is the measure of how much charge must be put on the plate to produce certain potential difference between them: greater the capacitance, the more charge is required.
The SI unit of capacitance that follows the following equation (i), is the coulomb per volt (c/v):q = C/V ........(i).Where q is the charge on the plates of a capacitor, and V is the Potential difference between their plates.
This occurs so often that it is given a special name, the Farad (F) that is:1 Farad = 1 coulomb per voltOR1 F = c/v
A capacitor is used to store electric charge. The amount of charge that it stores is proportional to voltage - more voltage means more charge. The capacitance tells you how much charge the capacitor can store when there is 1 volt across it.
The capacitance of a capacitor is usually marked on the case and is in units of Farads. It is a measure of the capacity to store electric charge.
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.

Diffusion capacitance is the capacitance due to transport of charge carriers between two terminals of a device. - Amog This diffusion capacitance is due to depletion capacitance which is a function of forward bias applied to emitter junction of a transistor and due to diffusion capacitance which a function of transconductance of the transistor. Its value is 100 pF. Tirupanyam B.V

For the gate to change state, the gate capacitance must be charged or discharged. Since the transistor driving the gate has a certain amount of output impedance (resistance), this together with the gate capacitance forms an RC network. The gate capacitance must charge through the driver's output impedance, and this takes time. So, gate capacitance limits the maximum speed at which the device can be operated. Decrease the capacitance, and you can clock the device faster!

Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
due to the load gates capacitance values,there is a increased load capacitance on the driving gate
No. Capacitance vessels refer to site where most volume of blood is found. Veins are capacitance vessels.
The charge inside of a p-n diode with a connected voltage variety yields a capacitance is need to add circuit model of a p-n diode. The capacitance connected with the charge variety in the exhaustion layer is known as the intersection capacitance, in the same process capacitance connected with the abundance bearers in the semi impartial district is known as the dissemination capacitance.
