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.

Definition of a capacitance in mosfet?
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.
How do you calculate the stray capacitance?

What is meant by transistion and space charge capacitance of a diode?
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
Which junction has least junction capacitance?
point contact has the least junction capacitance
When did Capacitance Electronic Disc end?
Capacitance Electronic Disc ended in 1986.
What is the importance gate capacitance in CMOS device?
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!

What is the type of capacitance effect exhibited in P-N junction when it is reverse biased?
1. Transition capacitance 2. Diffusion capacitance 3. Space charge capacitance 4. Drift capacitance
What is the difference between self capacitance and mutual capacitance in the context of capacitive touch technology?
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.
What is the difference between capacitance and stray capacitance?
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.
Effects of stray capacitance in ac fan out?
due to the load gates capacitance values,there is a increased load capacitance on the driving gate
Are arteries often referred to as capacitance vessels?
No. Capacitance vessels refer to site where most volume of blood is found. Veins are capacitance vessels.
What is pn junction capacitance?
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.
