This arrangement permits
the pile to be taken apart very quickly.
_Charging, Work, and Duration of the Pile._--The inventor has made a
large number of experiments with solutions of bichromate of potash of
various degrees of saturation, and has found the following to give the
best results:
Bichromate of potash. 1 kilogramme.
Sulphuric acid 2 liters.
Water 8 "
When a larger quantity of the salt is used, crystallization occurs in
the pile.
Constants and work Constants and work
of an element of a round Bunsen
having a zinc of element, 20x30 cm.
16x20 cm.
Volts. 1.9 1.8
Resistance. 0.05 0.24
Work disposable in the
external circuit. 1.839 k. 0.344 k.
The work disposable in the external circuit is deduced from the
formula:
T = E squared/(4R x 9.
