| Description |
English: Anode characteristic curves of the RCA 24-A tetrode vacuum tube. It shows the plate current (Ib) as a function of plate voltage for different values of control grid voltage (EC2). The lowest curve shows the screen grid current (IC2). This early tetrode illustrates the negative resistance "kink" in the plate current (labeled "values unstable") caused by secondary emission of electrons from the plate, that caused instability and parasitic oscillations in early tetrodes. Modern tetrodes have a coating on the plate which suppresses secondary emission, eliminating the "kink". |

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “RCA 24-A Screen Grid tube anode characteristics.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
This graph image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
