Thinking about squared rods of silver with 3mm wide, emerged about 7cm in the solution. 1) What is considered small and large electric current ? 2) The yellowish color of the solution is a good or bad indication ? 3) Using a green laser i can see a kind of faint cloud or a cloud filament spreading from the anode (-). Assuming that this can act as a kind of 'short circuit' i stir the solution, witch results at diminish of the electric current. As we prefer lower currents. All this make sense ? Thanks.
