C battery (vacuum tubes)

From Wikipedia, the free encyclopedia

 

In electronics, a C battery is any battery used to provide bias to the control grid of a vacuum tube. Until the early 1930s this was common practice in valve (tube) radio sets but was largely superseded by grid leak resistors or voltage divider biasing.

Strangely, Grid Bias batteries are still manufactured today, but not for radio use. They are popular in schools and colleges as a convenient variable voltage source in science clases. The most popular battery is the 9 volt type with taps every 1½ volts that accept a banana plug.
