Fig. 16. the acid the silver is dissolved away, leaving a platinum elec-trode of microscopic dimensions immersed in the liquid. If dilutesulphuric acid is employed, then an iron-coated platinum wire isused. If a small electromotive force is applied to such a cell bymeans of a shunted voltaic cell, B, and a telephone, T, or sensitivegalvanometer included in the circuit, a small current will flowthrough the electrolytic cell, E, and will polarise the electrodes,which will thereupon reduce the current practically to zero (seeFig. 16). Under these conditions, if oscillations are sent throughthe electrolytic cell they destroy the polarisation of the smallelectrode and the current suddenly increases, but it returns to itsformer small value as soon as the oscillations cease.
