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
What is the difference between ac and dc generator
In an AC generator, the energy produced in the generator is extracted directly through rings and brushes which are further connected to the output circuit. In the DC generator, the switch
how do transformers work
The transformer is a static device that converts electrical energy from one circuit to another without changing its frequency. it raises (or decreases) the voltage and current level. The transformer
What is better than LED lights? what will replace led lights?
LED lighting would be the white laser technology that could replace LED lighting in the architectural lighting and automotive (headlamp) sector in the future. BMW has already used the White
What are the differences between UJT and FET
Differences between UJT and FET. ujt (transistor at a junction): it is a transistor with a single junction and three terminals: a transmitter (e) and two bases (b1 and b2).
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
Can we harness energy from lightning?
With current technology, you can not use flash energy as an electrical energy source. Simply because lightning has a tremendous amount of energy and it is very difficult to collect
difference between NMOS PMOS and CMOS transistors
NMOS is constructed with the n-type source and drain and a p-type substrate, while PMOS is constructed with the p-type source and drain and an n-type substrate. In an NMOS,
What does recovery mode mean on a thermostat?
The recovery mode is when the thermostat prematurely turns on the heating / cooling so that it reaches the set point at the scheduled time. In other words, you set
What will happen if a DC voltage is given to the transformer primary?
When DC power is supplied to the primary transformer, no self-induced EMF is generated (no back EMF). Therefore, in the primary winding of the transformer flows a strong current, which
What is the function of a capacitor in a fan?
The fan has an AC motor. Now, when a capacitor is added to the additional auxiliary winding of the stator, a field is created which goes 90 degrees to the
what is the difference between ac and dc current
DC is a current that flows from a higher potential source to a lower potential load in a positive to negative direction. The alternating current is unidirectional. It changes the
Why AC supply is used in homes?
Edison suggested that households be supplied with direct current. However, it is not advisable to use DC because it is extremely difficult to increase or decrease the power distribution requirement.
