Question

what is function of grid in CRO??​

Answer 1

hai...

The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode.

The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its reliability, stability, and ease of operation make it suitable as a general purpose laboratory instrument.

thank you

Answer 2

Function of grid in CRO.

• grid: An electrode with openings for regulating the flow of ions or electrons via it in an electron tube. Unaltered, the word refers to a control grid that is often positioned between an electron tube's cathode and anode (or plate) to adjust the current flow.
• The control grid acts as a "gate" to regulate the current of electrons travelling from the cathode to the anode. Fewer electrons will pass through to the anode as a result of a larger negative grid voltage, which will force electrons back toward the cathode.
• a pattern of intersecting horizontal and vertical lines that results in a collection of squares. A grid is also a network of wires used to connect various regions of a country with electricity: a power grid.
• A zone of positive charge is created as a result of the grid potentials being chosen to repel electrons from the space between the grids. This eventually restricts the amount of current that can be extracted since the field induced by these charges cancels out the applied field.
