Summary

[edit]
Description
English: Voltaic pile demonstration in "cup crown" configuration (only one cup element). Used electrolyte is vinegar instead of the harmful sulphuric acid. This single element's generated voltage (0.95 V in open circuit) and current (4 to 2 mA when shorted) are enough to power a greetings card melody generator, which draws only 0.25 mA, but can't lit a lamp bulb nor a LED.
Español: Demostración de pila de Volta en configuración de "corona de vasos" con un único vaso. El electrolito utilizado es vinagre en lugar del peligroso ácido sulfúrico. La tensión (0,95 V en circuito abierto) y corriente (de 4 a 2 mA en corto circuito) que se obtienen de este único elemento son suficientes para alimentar el generador de melodía de una tarjeta de felicitaciones musical, que absorbe sólo 0,25 mA, pero no pueden iluminar una bombilla ni un LED.
Italiano: Dimostrazione di pila di Volta a "corona di tazze" con un solo elemento a tazza. L'elettrolita utilizzato è aceto anziché il pericoloso acido solforico. La tensione (0,95 V a vuoto) e corrente (da 4 a 2 mA in cortocircuito) generate da questo unico elemento sono sufficienti per alimentare il generatore di melodia di un biglietto augurale musicale, che assorbe solo 0,25 mA, ma non possono accendere una lampadina né un LED.
