What are the advantages of FET over transistor?
Advantages of fet over bjt In This post we are going to learn about what are the advantages and disadvantages of FET over transistor. Advantages of fet An advantage of the FET is its high gate to main current resistance…
What is the difference between MOSFET and FET?
Difference between mosfet and fet Mosfets are one type of fets. Fets in general are field effect transistors, which means that they are controlled by an electrostatic field induced by the applied voltage between the gate and its source terminals. In…
What is the use of substrate in FET and MOSFET?
A finer question would be what is the purpose of the substrate in a semiconductor device? and the answer is that is the foundation on which you fabricate a chip. Let’s understand in details on use of substrate in FET and…
What is the difference between MOSFET and HEMT?
In this topics we will understand what is difference between MOSFET and HEMT? Defination and use of Mosfet Mosfet (metal-oxide semiconductor field-effect transistor, pronounced maws-feht) is a special type of field-effect transistor (fet) that works by electronically varying the channel width…
What are the pros and cons of BJT versus FET transistors?
For pros and cons of BJT versus FET transistors first we needs to know whats its use in circuit and then we can understand benefit and losses of BJT vs FET transistors. Use of Bjt: this is the best device in…
Is the transformer an electric machine?
Machines: motors are machines (single electrical component), computer are machines (no moving parts). Therefore: what is a machine? need not consist of several parts, no need to have moving parts. And yet, the origine of the word means a technical…
Can a pulsating DC be used in a transformer? If not, why?
Yes, it can. This principle is used in some theories of dc-to-dc converters, it seems this might not work well, because the transformer output follows the input current derivative – meaning that pulsed dc input may be expected to produce…
What is a transformer and what is the difference with a generator?
The engine generates power from the fuel source while the gearbox changes and distributes power = torque * speed or t1n1 = t2n2 to the wheel. both the gearbox and the transformer are constant power (v1i1 = v2i2) devices whereas…
What kind of transformer?
Transformers can be classified on different basis, like types of construction, types of cooling etc. (1) on the basis of construction:-transformers can be classified into two types as; core type transformer shell type transformer Use of core type transformer In…
What is the use of transformers?
Transformer has its own important in the present arena as per the requirement and application the transformer has used as Uses and application of transformer The most important uses and application of transformer are: Can rise or fall the level…
What is a Varicap diode?
In electronics, a varicap diode, a varactor diode, a variable capacitance diode, a variable reactance diode or an adjusting diode is a diode type designed to exploit the voltage-dependent capacitance of an inverted p-n junction. The varators work in a…
How does the diode work?
When we talk about electrical and electronic circuits, we use the old convention, called the conventional current flow (from positive to negative). To get rid of any idea of thinking about “electrons,” we say “electricity flows from positive to negative.”…
Why zener diode is used?
Zener diodes are widely used as voltage references and as shunt controllers to adjust voltage across small circuits. When connected in parallel with a variable voltage source so it is inverse, a Zener diode leads when the voltage reaches the…
