What is a vacum tube?
A vacuum tube is an electronic component that was used in early electronics to control the flow of electrical current. It consists of an evacuated glass enclosure containing electrodes such as a cathode, anode, and grid. Vacuum tubes were widely used in early radios, televisions, and computers before being largely replaced by semiconductors.
What is vacuum tubes define?
Vacuum tubes are electronic devices that control the flow of electrons in a vacuum. They were widely used in early computer and radio technology before being replaced by transistors. Vacuum tubes can amplify signals and are known for their warm, vintage sound in audio equipment.
Who invented the vaccum tube?
The vacuum tube was invented by Thomas Edison in the late 19th century. However, it was not until Lee de Forest's modification in 1906 that the vacuum tube became an essential component in early electronics.
Is refractive index of air less than vacuum?
No, refractive index(RI) of air is more than that of vaccum. Infact RI of any medium is more than vaccum. RI of vaccum is 1. RI of any medium = c/v where c is speed of light in vaccum v is speed if light in medium whose RI with respect to vaccum is found. It is known that speed of light is maximum in vaccum so v < c, and RI > 1.
Why are hollow tubes used instead of solid steel tubes?
Hollow tubes are used instead of solid steel tubes to reduce weight while maintaining structural strength. This makes them more cost-effective and efficient for various applications, such as construction, automotive and aerospace industries. Additionally, hollow tubes allow for easier passage of fluids, wires, or other elements through the center.
Write the key points of first generation computers?
First Generation computers were made out Vaccum Tubes. They required alot of Electricity and emitted a lot of heat. Vaccum Tubes were also needed to be replaced when it becomes really hot. So Vaccum Tubes were not very efficient or easy to handle.
What are the Components of first generation of computers?
vaccum tubes and valves.
What is vacum tubes?
a vaccum tube is really really niceeee
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
What is microwave tube?
microwave tubes are sometime called as vaccum eletrpn device... that are used to generate or amplify microwave radio frequencies.
1990 Nissan 300zx What if the AC works but will not change from the dash vents to the floor vents or defrost wents you I have replaced the climate control switch?
ITS THE VACCUM ADVANCE WHEN YOU ACCELERATE THE VACCUM IS LEAKING WHEN YOU RESUME SPEED THE A/C REACTS NORMAL CHECK VACCUM HOSE LEAKS
What components has the transistor replaced?
Mainly vacuum tubes.
In what way did alan turing and john von neumann improve upon the design of the eniac?
He improved upon the design by adding Vaccum Tubes
What was the chief component of first generation computers?
the vacuum tube ( valve) used to store data ( like 50 kilobytes )
Transistors replaced to amplify electric signals?
vacuum tubes
What are the first generation computer?
First Generation computers were computers made out of Vaccum Tubes. They were soon rejected due to the extreme heat and electricity absorption.
What device in a CPU uses a lot of power and gives off a lot of heat?
Vaccum tubes use a lot of power and give off heat.
