THERMIONIC VALVE SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Vakum tüpü
Elektronikte, vakum tüpü, elektron tüpü, tüp veya vana, kapalı bir kapta bulunan vakum boyunca elektrik akımını kontrol eden bir cihazdır. Vakum tüpleri çoğunlukla, sıcak filament veya filaman tarafından ısıtılmış bir katottan gelen elektronların termiyonik emisyonuna güvenir. Bu türe bir termiyonik tüp veya termiyonik valf denir. Bununla birlikte, bir fototube, fotoelektrik etki yoluyla elektron emisyonuna ulaşır. Tüm elektron tüplerinde vakum yoktur: Gaz dolu tüpler, iyonize edilmiş bir gaz yoluyla bir deşarj özelliğine dayanan cihazlardır. En basit vakum tüpü olan diyot, yalnızca iki elemanı içerir; akım, sıcak katottan yayılan elektronlar tüpün içinden geçerek anod ile toplanır ya da konvansiyonel akım terimleriyle anoddan katottan aktığı için iki elektrod arasında cihaz boyunca tek bir yönde akabilir. Katot ve anod arasında bir ızgaralı veya daha fazla ızgaralı borular, iki elektrot arasındaki akımı kontrol etmeye izin verir. Izgaralı borular, elektronik amplifikatörler, redresörler, elektronik kontrollü anahtarlar, osilatörler gibi diğer amaçlar için kullanılabilir.
İngilizce sözlükte thermionic valve sözcüğünün tanımı
Sözlükteki termiyonik valfin tanımı, elektronların soğuk bir katottan ziyade ısıtılmış olduğu bir elektronik valfdir.
