Abstract

Un tubo de descarga eléctrica cuyo lastre está constituido por una resistencia de coeficiente de resistencia positivo elevado con la temperatura para compensar o compensar con exceso el coeficiente de resitencia negativa del tubo de descarga.An electric discharge tube whose ballast is constituted by a resistance with a positive coefficient of resistance elevated with temperature to compensate or overcompensate for the negative coefficient of resistance of the discharge tube.
