What is the control grid?

The control grid is simply listed by an electric conductor used in vacuum tubes. It is an electrode that modulates the flow of electrons in the circuit of the board, or more specifically in the circuit of the cathode to the anode. The control grid is an integral part of vacuum tubes that are used in many electronic applications such as radio broadcasts, computers, TVs, industrial processes, radars, phones and sound reproduction.

The vacuum tube is any device that controls the movement of electrons to create, increase, transmit or modify electrical signals. The electrons are contained in a low -pressure, vacuum space and therefore the term "vacuum tube". There is an anode or metal plate that is positively charged, and a cathode or fiber that is negatively charged. The electrons flow from the "hot" fiber to the "cold" plate or from the cathode to the anode. Because of this one -way flow, a diode is formed. The control grid, as stated, is the mechanism that modulas electron flow in the diode.

in the SeveRhno America is also called electron tubes and in the UK they are called thermionic valves. The simplest vacuum tubes look like bulbs; They have a fiber in a glass envelope, vacuum space and a metal plate. Over the years, changes in the vacuum tube have been created to increase more efficient. Now there are "soft tubes" that are full of low -pressure gas.

The

control grille is located in the vacuum tube to adjust the anode current. With the addition of a grid in the diode, the assembly is now becoming a triod. Because the control grille is an electrode or conductor, it acts as a mechanism of bridging between the anode and the space in the tube. It can cause changes in the anode current by setting its voltage. Even very small voltage changes can cause significant current fluctuations.

A simple control grid usually consists of a zigzag piece of wire that leads from the fiber to the anode. SophisticatedTypes can look like a hellic net that connects a cylindrical cathode with a cylindrical anode. The grid is often made up of very thin wires that are highly resistant to heat. These wires are usually plated with gold to withstand heat and prevent them from emitting electrons. The control grille can be located closer to the cathode, resulting in a larger and faster stream amplification. There may also be more than one control grid in the vacuum tube.
