Grid tube contains a grid between the cathode and anode, allowing the current flowing through the tube to be controlled.
The three main tasks carried out by electric grids are electricity generation, transmission, and distribution. The first step in distributing electricity is power generation, which is carried out at power plants (coal, nuclear, geothermal, hydro, and so on).
Research-related organizations are cataloged in the free, publicly accessible, and worldwide GRID database, which also assigns each organization a distinct, long-lasting identification. The usage of a variety of resources, even those that are located distant from where the power is needed, is made possible by the energy grid. For instance, wind turbines must be installed where the wind is greatest so that it can be transferred via the grid to distant towns.
