Space charge limiting effect

…The current is limited by the negative charge created by the electrons themselves in the space between the electrodes and is approximately proportional to the 3/2 power of the anode voltage. This is called the space charge limiting effect, and is the basis for determining the current values ​​of various electron tubes. At high anode voltages, the effect of space charge can be ignored, and the current is approximately constant regardless of the anode voltage. …

*Some of the terminology that refers to the "space charge limiting effect" is listed below.

…電流は電極間空間に電子自身の作る負の電荷に制限され陽極電圧のほぼ3/2乗に比例する。これを空間電荷制限効果といい，種々の電子管の電流値を定める基礎でもある。陽極電圧の高いところでは空間電荷の影響は無視でき，電流は陽極電圧に関係なくほぼ一定となる。…
