How many vacuum tube in one transistor?
There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.
Electronic system used in multiplex theatres?
electronic system used in multiplex theatres
Where are simple circuits used?
Simple electronic circuits are used in simple electronic devices.
What theorem is used in vacuum tubes?
Millman's theorem
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
What do you use in a vacuum to bend electronic beams?
Either an electrostatic field or a magnetic field. Each type is used in cathode ray tubes: generally, electrostatic in oscilloscopes, magnetic in television and computer CRTs.
What was the first electronic computer that used vacuum tubes?
ENIAC
Which vacuum cleaner used for electronic panel cleaning?
3M Produces an electronic Vacuum cleaner. Just google 3m electronic vacuum cleaner and it will show up. Do not confuse this for being safe for cleaning live circuits. It is just ground protected to not short out circuitry.
What was the first electronic device used as a switch in the first digital computers?
vacuum tubes
What is the temperature sensitive resistor commonly used on vacuum gauges is called a?
Electronic Thermister
What were Vacuum tubes used for?
Vacuum tubes were used back in the 19th century and mid-20th century for a number of things. At first they were used just in scientific areas, but then they were used as electronic amplifiers. They were eventually used in the first computers.
What is an electronic vacuum pump?
An electronic vacuum pump is a device designed to create a vacuum or low-pressure environment using electronic components and mechanisms. These pumps are often used in applications such as automotive systems (e.g., brake boosters), air conditioning, and various industrial processes. Electronic vacuum pumps can operate independently or be integrated into larger systems, providing controlled suction and pressure conditions for specific applications. They play a vital role in ensuring the proper functioning of systems that require a vacuum, such as in automotive brake systems where they assist in enhancing braking efficiency.
What electronic device used as a switch in the first digital computer?
vacuum tubes
What tool do scientist use to measure mass with?
Archaically , a Balance. ( An old fashioned style of scales). In modernity , a 'top-pan' electronic balance.
What are the Uses of laser beams?
What are three things laser beams are used for?
What gem is commonly used in creating laser beams?
Diamonds are commonly used in creating laser beams.
What is an i beam?
I-beams are divided into ordinary I-beams, light I-beams and H-beams. I-beams are mainly used in crossbeam construction. Shanghai Changzheng produces I-beam, if you are interested in I-beam, welcome to consult with our company.
