What happens to an inductive circuit when capacitance is added for power factor correction?
The capacitance counter acts the inductivity (decreases it) without impacting the resistivivity, thus increasing the power factor, or resistivity / inductivity ratio.
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?
stray capacitance calculation
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
What is the ratio of capacitance of capacitors?
ratio of capacitance of capacitor is given by charge\potential
What hapens to capacitance whe the voltage increases?
Capacitance is the ratio of charge to voltage, and is a constant. So, nothing will happen.
What happens to a capacitance if the plates have a charge that is doubled?
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.
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
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.

Which physical property is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential?

What is capacitance?
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.
Define capacitance with respect to physical structure and electrical function?
capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. The resulting unit of capacitance is the farad [for Michael Faraday]. In an electric circuit the device designed to store charge is called a capacitor. An ideal capacitor, i.e., one having no resistance or inductance, may be spoken of as a capacitance. When an alternating current flows through a capacitor, the capacitor produces a reactance that resists the current (see impedance). While every element of a circuit has some capacitance, it is a goal of good design to reduce such unwanted or stray capacitance to a minimum.
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
How do you calculate the stray capacitance?
stray capacitance calculation
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.
