The difference between a Field Effect Transistor and a regular transistor is that the regular transistor has PNP and NPN junctions and a FET has just a Drain Source Gate
junction and is sensitive to static electricity just as not as bad as a MOSFET. Soldering
a FET requires technical skill than it does a regular transistor. Transistors are used in switching and audio applications while FET's are used in RF VHF and HF applications and switching on high current devices such as LED's and piezo buzzers.
So a one transistor radio using a PNP transistor does not mean you will pick up more stations you will just receive a weak audio voltage through the high impedance earphone from the simple diode circuit using a 9 volt battery. While FET's and MOSFET's will amplify the signal.
MOSFET's are for really high current devices that's why have heat sinks on top of them.
What else can I help you with?
What is the center section of a transistor called?
in bipolar transistors it is called the basein field effect transistors it is called the channel
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.
Matched pair of transistors is particularly useful for?
A differential input stage employing matched pairs of field effect transistors provides a high input impedance, good dc stability and is sufficiently simple and robust for student use.
Why do we not use point-contact transistors?
Point-contact transistors are largely obsolete due to their limited performance and reliability compared to modern bipolar junction transistors (BJTs) and field-effect transistors (FETs). They are more susceptible to thermal instability and noise, which can affect their operation in electronic circuits. Additionally, advancements in semiconductor technology have led to the development of more efficient and compact devices that offer better performance, making point-contact transistors less viable for contemporary applications.
How many types of field effect transistor?
There are two types of field effect transistors:junction field effect transistors andmetal-oxide semiconductor field effect transistors.
What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.

What are the two main types of transistors?
The two main types of transistors are bipolar junction transistors (BJTs) and field-effect transistors (FETs). BJTs operate by controlling the flow of current via two types - NPN and PNP. FETs control current flow using an electrical field, with types including MOSFETs and JFETs.

In a microprocessor, field-effect transistors behave as electrically-controlled switches.
