Which electronic has three terminal and is made of semiconductor material?
A transistor is an electronic component that has three terminals and is made of semiconductor material. It is used to amplify or switch electronic signals and power, playing a crucial role in modern electronic devices. Transistors can be found in various configurations, such as bipolar junction transistors (BJTs) and field-effect transistors (FETs).
Why narrow gap semiconductors have large dielectric constant?
The dielectric constant measures how strongly the eletronic charge in the material can adjust to shield an external electric field, larger the dieletric constant, more effective is the screening. But for the electronic charge be able to adjust responding to the electric field, the electrons should be easily moved, which means that each electronic state will change assuming a polarized configuration. If the gap is large, the electric field can not mix the electronic states in the valence band with the electronic states in the conduction band, (think of perturbation theory, where the denominator will be of order of the band gap energy) so the electrons don't polarize much and the dielectric constant is small. On the other hand, in a metal, where the gap is zero, any small electric field mix the occupied states with the unoccupied ones, and we have a strong screening.

What is the main career in electronic engineer?
A: There is none because of the variety and diversity of fields to be interested in. It is up to the individual the field of electronics that he she be happy with.
What kind of materials does one need to build solar panels?
In order to build solar panels one needs to find materials capable of being semiconductors. It is common to use silicon as the main material for this combined with using metal electrodes to create the required electronic field. Scientists have recently been experimenting with other materials such as plastic or organic polymers as they can be less expensive to produce.
Inventing is what branch of science studies for Thomas Edison?
Thomas Edison focused on inventions that were basically in the field of electrical and chemical engineering. He worked with a number of scientists in these fields.
Who is the famous scientists that contributed many to the field of science?
Thomas Edison
What is meant by the culture of telecommunication?
telecommunication is the assisted transmission over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags or heliograph. In modern times, telecommunication typically involves the use of electronic devices such as the telephone, television, radio or computer. Early inventors in the field of telecommunication include Alexander Graham Bell, Guglielmo Marconi and John Logie Baird. Telecommunication is an important part of the world economy and the telecommunication industry's revenue was estimated to be $1.2 trillion in 2006.
Is electronics and telecomunication field good for job?
Yes, this is very wide and major field in current days all systems and organizations used automation system which required electronic equipment and control system so the demand of Electronic engineers are increasing rapidly . while telecommunication branch deals with communication technology telephony and telegraphy.
Who are the famous scientists that contributed to the field of classifications?

What does CRAC stand for with in the telecommunication field?
CRAC is the Acronym for Computer Room Air Conditioner
Who are some famous scientists who contributed in the field of electronics?
Some famous scientists who significantly contributed to the field of electronics include Thomas Edison, known for inventing the first practical incandescent light bulb and the phonograph; Nikola Tesla, who developed alternating current (AC) electrical systems; and John Bardeen, who co-invented the transistor, a fundamental component in modern electronics. Other notable figures include Alan Turing, known for his work in computing and cryptography, and Robert Noyce, co-inventor of the integrated circuit, which revolutionized electronic devices.
What are the things scientists do to contribute to their dedicated field of science?
Scientists do research, publishing, and teaching, to contribute to their field.
What is the difference between telecommunication and teleconferencing?
Telecommunication refers to the broader field of transmitting information over distances through electronic means, including various forms such as phone calls, emails, and internet data transmission. Teleconferencing, on the other hand, specifically involves real-time communication among multiple participants using audio, video, or both, often facilitated through digital platforms. Essentially, while telecommunication encompasses a wide range of communication methods, teleconferencing is a specific application of those methods for group interactions.
