The only difference between these two cells was that in Lenard's cell the electrons were taken from the cathode by light, whereas on the "3-electrode lamp" the cathode is a white-hot filament capable of sending into the vacuum currents of much higher intensity.

在研究過程中，萊納德還發(fā)明了一種光電管无码免费毛片一区二区，以加速電子和測量它們的能量日韩色色图片，這種光電管是三極管最初的雛形毛茸茸性XXXX，不同之處在于中文字幕在线第一区，在萊納德的光電管中，電子是由陰極光發(fā)射的可以免费观看一级毛片黄a，而三極管中的陰極是白熾絲影音先锋国产一二三区资源，可以向真空發(fā)射更高強度的電流。

A filament that emits electrons thermionically may be disposed around the rod in close proximity to the cathode.

一發(fā)射熱電子化電子的絲極在靠近陰極處安裝在支撐桿周圍视频一区在线看。

In ancient times, when vacuum tubes were still in use, the A battery (often about 6 volts) heated the filament or cathode to boil off electrons, the B battery, positive with respect to the cathode, sucked the negative electrons to the plate, while the C battery, a few volts negative with respect to the cathode, tended to repel the electrons back toward the cathode.

古時候人人摸人人操人人干人人，還在使用真空管時，A電池（通常為6V）通過加熱燈絲或陰極來蒸發(fā)電子91POPNY老熟女国产，B電池偷拍一区1页，正極連接陰極，將負電子吸引到極板上人人看人人草人人搞人人鲁人人插，而C電池A级高清免费毛片av无码，只有幾伏，負極連接陰極99re，將電子擊回陰極A片黄网站。
