CHE SIGNIFICA PENTODE IN INGLESE
pentodo
Un pentode è un dispositivo elettronico avente cinque elettrodi attivi. Il termine più comunemente si applica a un tubo a vuoto di amplificazione a tre griglie, inventato dall'odernetto Bernhard DH Tellegen nel 1926. Il pentode è costituito da una busta di vetro evacuata contenente cinque elettrodi in questo ordine: un catodo riscaldato da un filamento, un controllo Griglia, griglia di schermo, griglia di soppressori e piastra. Il pentode è stato sviluppato dal tubo tetrode con l'aggiunta di una terza griglia, la griglia soppressore. Questo serve a impedire che gli elettroni di emissione secondaria emessi dalla piastra raggiungano la griglia dello schermo, che ha causato instabilità e oscillazioni parassitarie nel tetrode. Il pentode è strettamente legato al tetrode del fascio. I pentodi sono stati ampiamente usati in apparecchiature elettroniche e di consumo elettroniche come le radio e le televisioni fino agli anni '60, quando sono stati sostituiti da transistor. Il loro uso principale è ora nelle applicazioni industriali ad alta potenza come i trasmettitori radio. I tubi di consumo obsoleti sono ancora utilizzati in alcuni dispositivi audio del tubo vuoto e speciali.
definizione di pentode nel dizionario inglese
La definizione di pentodo nel dizionario è una valvola elettronica con cinque elettrodi: un catodo, un anodo e tre griglie. L'altra definizione di pentodo ha tre terminali alla base o alla porta.
