yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
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]
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.
Roughly speaking, resistance. Transconductance refers to the reciprocal of the amplifying device's internal resistance. The concept is particularly useful if the device is a voltage-controlled current source (tube or FET). In vacuum tube amplifiers, transconductance (Gm) is (u / Rp), where... u is the amplification factor. u= (Gm x Rp). Rp is the anode (drain) resistance. Rp is the internal resistance of the amplifying device. Gfs is synonymous with Gm. The reciprocal of Gm (or Gfs) is (Rp / u). Another term for this reciprocal is transresistance.

J.J. Thomson is credited with creating the first beam of electrons in a vacuum tube in the late 19th century. This discovery led to the development of the cathode ray tube, which was integral to the development of television and other electronic displays.

the vacuum tube
The grid current in a vacuum tube increases as the grid voltage becomes more positive and decreases as it becomes more negative. Excessive grid current can damage the tube and cause distortion in the output signal. It is important to operate vacuum tubes within their specified grid current limits to prevent damage.
A Transistor is an electronic device which amplifies electrical signals, or acts as a switch. Most of the research on Transistors was performed by Shockley in 1947. That was when, the advantages of the solid state device similar in function to a Triode Vacuum tube were understood and implemented. The basic advantage was compactness..

Tube count refers to the number of vacuum tubes or electron tubes present in an electronic device. Vacuum tubes are electronic components used to amplify, switch, or create electrical signals in various electronic devices such as radios, televisions, and amplifiers. The tube count helps determine the complexity and functionality of the electronic device in which they are used.
Vacuum tubes are non-ohmic devices because their resistance changes with voltage and current. This non-linearity in resistance is due to the nature of the electron flow within the vacuum tube, causing it to exhibit non-ohmic behavior.
Yes; solid state rectifiers were made using values (also called vacuum tubes). ************************************************************* A solid state device is a semiconductor device. A valve (vacuum tube) is a thermionic device, so yes, rectification can be achieved with a thermionic rectifier.
