Nope, still backwards...
Assuming distilled water
The starting current will be almost nil.
As silver starts to accumulate, the current will INCREASE as the
process continues due to the silver increasing conductance in the
water. It ramps up from near zero.
The increase will continue 'till it reaches runaway, where it
increases very rapidly.
Even with current control, the starting current will be small until
there's enough silver in the water to affect the conductance.
It ramps up to the limit.
Then the limiter will do it's thing and keep the current constant.
