CONT

Debido al fenómeno de la emisión secundaria de electrones, cuando la tensión de ánodo no es suficientemente elevada, se produce la distorsión alineal que observamos en la curva de características del tetrodo. Para evitar precisamente este inconveniente, se inventó un nuevo dispositivo llamado pentodo, al que se le añadió un nuevo electrodo entre ánodo y rejilla pantalla, llamado rejilla supresora.
