Butler is "The butler did it!" The best-known fictional manservant, and the archetype of the quintessential British butler, is himself not a butler at all. Reginald Jeeves, the iconic creation of author P. G. Wodehouse is a "gentleman's gentleman" and general factotum. Probably the best-known fictional butlers are Alfred from the "Batman" comic and films; Hudson of Upstairs, Downstairs television fame; Mr Carson from the Downton Abbey television series; and Crichton from J. M. Barrie's "The Admirable Crichton". Lesser-knowns include Mr. Belvedere from the novel "Belvedere", which was adapted into a feature film with sequels and later a television series; Lurch,
Butler–Volmer equation the surface is equal to that in the bulk. There are two limiting cases of the Butler–Volmer equation: where formula_21 and formula_22 are constants (for a given reaction and temperature) and are called the Tafel equation constants. The theoretical values of the Tafel equation constants are different for the cathodic and anodic processes. However, the Tafel slope formula_22 can be defined as: where formula_25 is the faradaic current, expressed as formula_26, being formula_27 and formula_28 the cathodic and anodic partial currents, respectively. Butler–Volmer equation The Butler–Volmer equation (named after John Alfred Valentine Butler and Max Volmer), also known as Erdey-Grúz–Volmer
