An Experiment on electrolysis utilizing low energy capacitive pulses
Author(s): Parantap Nandi
Abstract: Electrolysis relies on the migration of ions towards oppositely charged electrodes (anode and cathode) under the influence of applied electric field. This (the field) is obtained from a D.C source rated for a suitable voltage and current supplying capability. The energy supplied to the electrolyte is high of the order of Joules (may be in the order of hundreds or thousands). The supply is maintained continuous. All these occur when the supply is D.C. The fixed and well defined polarity of D.C allows the ions to migrate in a definite manner. But A.C does not have a fixed polarity. Yet A.C can charge a capacitor. A charged capacitor when kept open circuited retains the charge for a very long time. Energy is stored in the electrostatic field. This energy is very small in magnitude ranging from µJ to a few mJ. When discharged using a resistive load, the energy dissipates in the load without oscillation. If the load is an electrolyte, the released energy causes electrolysis of the solution. This paper describes the characteristics of electrolysis using capacitive discharges under low energy conditions.
