The ratio between the charge on either plate of a capacitor (Q) and the potential difference (V) across the plates is given by the capacitance (C) of the capacitor, expressed as ( C = \frac{Q}{V} ). This means that the capacitance is a measure of how much charge a capacitor can store per unit of voltage applied. Therefore, the ratio ( \frac{Q}{V} ) is constant for a given capacitor and is equal to its capacitance.
The capacitance counter acts the inductivity (decreases it) without impacting the resistivivity, thus increasing the power factor, or resistivity / inductivity ratio.
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
ratio of capacitance of capacitor is given by charge\potential
Capacitance is the ratio of charge to voltage, and is a constant. So, nothing will happen.
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.

The capacitance won't change, or it won't change significantly. The capacitance is simply the charge/voltage ratio - and if the charge doubles, the voltage will also double. Capacitance is determined by the physical properties of the capacitor (plate separation, plate area, and dielectric). The unit for capacitance (farad) is a coulomb per volt. So the capacitance is the amount of charge (coulombs) that the plates will hold at a given voltage.
The physical property defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential is capacitance. This property is measured in farads (F) and it quantifies how much charge can be stored per unit voltage.

Theoretically, Capacitance is defined as the ability of a component or circuit to collect and store energy in the form of an electrical charge. Mathematically, it is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential.
Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.
