What is the difference between vacuum tubes and transistors?
A vacuum tube is a current amplifier where the transistor amplifies voltageA tube is a voltage amplifier. A transistor is a current amplifier. A tube is an older design that requires substantial voltage to operate correctly. A transistor is a semiconductor device that operates on relatively low voltage.
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.
How does a vacuum tube work?
contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. Adding one or more control grids within the tube allows the current between the cathode and anode to be controlled by the voltage on the grids.[5]
How can you replace transistor with vacuum tube?
A: ABSOLUTELY but only in its function . To implement a change requires additional power requirements and design
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
Disadvantages using a vacuum tube method venipuncture?
Sometimes the vacuum collapses the vein.
What computer component did the transistor replace?
the vacuum tube
What type of pressure gauge can measure vacuum pressure?
A Bourdon Tube or a Bellows gauge
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What is in a vacuum tube?
Millman's theorem
How can you measure the diameter of capillary tube by using vernier caliper in traveling microscope?
To measure the diameter of a capillary tube using a traveling microscope and vernier caliper, place the capillary tube on a flat surface. View the capillary tube through the traveling microscope to measure the external diameter. Then, use the vernier caliper to measure the internal diameter by gently inserting the capillary tube between the jaws of the caliper to get an accurate measurement. Subsequently, calculate the average diameter using the two measurements.
Where was vacuum tube was made?
who made the vacuum tubes
How many KB is a vacuum tube?
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
How exactly does a vacuum coffee maker work?
A vacuum coffee maker sucks water using a vacuum tube through a filter with coffee grounds in it, making the water quickly turn into a rich flaavorful coffee.
How can you make a am transistor radio by using transistor?
You get two transistors and put them in a radio.
What are example of vacuum tube?
cellphone
