QUÉ SIGNIFICA WESTON STANDARD CELL EN INGLÉS
Célula de Weston
La célula de Weston, es una célula química húmeda que produce un voltaje altamente estable adecuado como un estándar de laboratorio para la calibración de voltímetros. Inventado por Edward Weston en 1893, fue adoptado como el estándar internacional para EMF entre 1911 y 1990.
definición de Weston standard cell en el diccionario inglés
La definición de celda estándar Weston en el diccionario es una celda primaria utilizada como estándar de fem, que produce 1.018636 voltios: consiste en un ánodo de mercurio y un cátodo de amalgama de cadmio en un electrolito de sulfato de cadmio saturado Nombre anterior: célula de cadmio.
