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

What is meant by drift current in diode?
when ever the external voltage is given the movement of charge carriers produce a current i.e drift current
What is meant by IN4007 diode?
The 1 stands for number of semiconductor junctions The N means it's a semiconductor diode
What is meant by the capacitance of a capacitor?
I'm not going to give you the mathematical description, just the general description. A capacitor is designed so that it can absorb a certain amount of electricity, in the way a sponge can absorb water. The specific amount that it can absorb is called its capacitance. This is a variation of the word capacity.
What is meant by z source inverter?
the z-source inverter use an input diode and x-shape network of capacitors and inductor
Why diode 0a79 is used in amplitude demodulation?
This is very old germanium diode and nomenclature comes before a standard had been established for semiconductors. They modeled 0A after the vaccum tubes where 0 - zero means 0Volts filament voltage and A meant single diode. Latter , semiconductor nomenclature come where the first number was telling a number of PN junctions followed by N (this is for US), Japanese and Europeans had different naming standards
What is meant by transition and space charge capacitance of a diode?
space charge region in a diode or say a bjt for better understanding is same as the depletion region, both transition capacitance and depletion capacitance are the same c= (epsilon*A)/d ; where ... c is capacitance A is area and d is the depletion width the other type of capacitance is the diffusion capacitance c= (T*I)/(n*V) where ... c is the capacitance T is transition ti me I is the drift current n is emission coefficient ... its value is 1 for germanium and V is thermal voltage .. 26mv
What is meant by the threshold point of a diode?
it means the entrance point of a diode
What is meant by drift current in diode?
when ever the external voltage is given the movement of charge carriers produce a current i.e drift current
What is meant by IN4007 diode?
The 1 stands for number of semiconductor junctions The N means it's a semiconductor diode
What is meant by the term capacitive resistance?
That term to me is incorrect it should be capacitance impedance. Resistance is linear impedance. CAPACITANCE will follow a vector caused by the capacitor value.
What is meant by 'OA' in OA79 and '1N' in 1N4001?
IN IN = 1N: Refers to the number of junctions (1N= 1 junction). O= Germanium, A= rectifier diode, so OA = germanium rectifier diode.
What is meant by 1 Coulomb?
A coulomb is defined as the amount of charge trasnported in one second by a 1 ampere current, the amount of charge in a 1 faradad capacitance charged by 1 Volt, or as 6.24150962915265 × 1018 elementary charges where an elementary charge is the charge of an electron or a proton. Unlike other types of physical quantities, there are actually 2 distinct types of charge, a negative and a positive. By historical definition, things with the same charge as an electron is called negative and the same charge as a proton is called positive. Therefore, something with a charge of -1 has the same net charge of 6.24150962915265 × 1018 electrons.

What is meant by stray capacitance?
ANSWER Stray capacitance is the capacitance in a circuit not caused by capacitor components. There is a small capacitive effect, often on the order of a few picofarads, between leads of ICs, traces on a PCB, wires in a cable, the power and ground planes in a PCB, etc. In high-speed circuits, stray capacitance can be enough to completely change the operation of a circuit -- even to the point of keeping it from working as designed. Note that capacitor "components" can include PCB traces specifically designed to act as capacitors.
What is meant by oxidation number?
Numerical charge on the ions of an element
What is meant by proton?
the positive charge present inside the nucleus of an atom having charge+1 is called proton
