What is a electronic device that is made of solid mateiral which electrons move through?
Any semiconductor device...eg: A transistor.
Why is a transistor called a pi-polar device?
a transistor is called a Bi-polar device because in this we use both p-type semiconductor and n-type semiconductor. In p-type semiconductor the current flows with the help of holes(deficiency of an electron or we can say it as a positive charge). while in n-type semiconductor the current flows with the help of electrons(negatively charged particles). so the total current is due to both kind of charge carriers. that's why it is known as a Bi-polar device.
What is the typical breakover voltage for a DIAC used in an electronic control circuit in which 120 VAC is used with a power output semiconductor device?
32
Why diodes and other electronic devices does not obey ohms law?
Acc to ohm's law-" current flowing in a conductor is directly proportional to the voltage applied across it till its temperature , pressure and other physical parameters are kept constant". This is the major factor ,current remains proportional to applied voltage till temperature is constant and while dealing with semiconductor devices like diodes and transistor , its temperature changes. When current flows within a semiconductor, due to the motion of electrons and collisions in the it, heat is produced and temperature of the semiconductor increases. As semiconductor have negative coefficient of resistance therefore its resistance starts decreasing with the increase in temperature. Hence with the decrease in resistance, its current starts increasing and device shows nonlinear behaviour. that's why ohm's law is not valid for semiconductor. while handling conductors, its temperature also changes as current flows from it but up to a certain range there is not an appreciable change in its resistance and it shows linear behaviour.
What does fpga stand for?
FPGA - Field-programmable gate array is a semiconductor device containing programmable logic components called "logic blocks", and programmable interconnects.
What is thermistor diode?
A semiconductor device that is particularly sensitive to changes in temperature, permitting it to serve as an accurate measure of temperature.
What is unipolar device?
bipolar devices use both majority and minority current carriersunipolar devices use only majority current carriers
What is NMO?
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
What is abbreviation NMOS?
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
What is surface leakage current?
Undesired current flow across the surface of a semiconductor device due to contamination of that surface. This disturbs the operation of the device and causes a variety of failures. Insulators can also have surface leakage current for similar reasons.
Which semiconductor power device is not a current triggered device?
Power FET
Which device uses a crystalline solid to control current?
Semiconductor
Which semiconductor device is used as a voltage regulator and why?
its simple to say a
Is a transistor a semiconductor device?
Unfortunately no, it is nonlinear. But with careful selection of bias point, etc. it is usually possible to find a limited range of operation in which it approximates linearity well enough to be acceptable for the application.
What is the difference between semiconductor and electronics?
A semiconductor is a device which is neither a Insulator nor a conductor. They behave like one in the right conditions.
What is the name of a semiconductor device having negative resistance?
A tunnel diode.
What is a electronic device that is made of solid mateiral which electrons move through?
Any semiconductor device...eg: A transistor.
