What is unidirectional device?
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
Is FET a bipolar?
no. its unipolar
Difference between bjt and ujt?
UJT is the voltage controlled device.in which only one mejority carriers are responsible for current flowing. UJT is one junction transistor and it is three terminal emitter and two base. BJT is the current controlled device. in which both mejority and minority carrier are responsiblefor current flowing. this type of transistor consists of two junction and three terminal these are : emitter , base , collector.
What applications would prefer the bipolar junction transistors over the field effect transistor?
bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt..... The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.
Why junction field effect transistor is called as unipolar devices?
Field Effect Transistors (both JFET & MOSFET) are unipolar because they use only one type of current carrier (electrons in N-channel or holes in P-channel), unlike bipolar transistors (both junction & the obsolete point contact) which always use both types of current carriers.
Is a diode a unipolar device?
No.
Is zener diode is unipolar device?
no...
What is the Difference between bipolar and unipolar electronic device?
?!
Is SCR the unipolar device?
SCR is bipolar device since current is due to both electrons as well as holes.
Why BJT is called bipolar device and FET an unipolar device?
FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.
What is unidirectional device?
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
Is the pn junction diode is a bipolar or unipolar?
diode is unipolar
Which of these neuron types are unipolar?
which of these neurons types is are unipolar
Why FET is called as a unipolar transistor?
The FET is a semiconductor device with the output current controlled by an electric field. Since the current is carried predominantly by one type of carriers, the FET is known as a unipolar transistor.
What is the difference between Unipolar NRZ and Unipolar RZ in the time domai?
what is manchester code
Indentify the three kinds of neurons that are found in the nervous system?
Unipolar, multipolar and pseudo-unipolar
What is unipolar depression?
Uni- one. unipolar depression - this is form of depression without maniacal episode
