Firstly, let me say, that I think
that "Constant Current" can be built into the design of
a colloidal silver generator, but constant current does
not have to be used in the design of all colloidal
ie. In the MProCSG unit, featured on this website, the
current slowly increases as the water gains more and
more silver particles (becomes more conductive). When
this increasing current reaches a predetermined amount
the unit switches off automatically. The result of this
is high grade colloidal silver at a repeatable
It is true that a "Constant Current" generator will
run at constant current at the end of the cycle when
that current is reached. See below for explanation of
this process. For most of the production the generator
should not be in the constant current mode. (see
Colloidal Silver Facts below)
I was trained in electronics and
have technical knowledge of the principles of Ohms Law.
Ohms Law is the relationship between applied voltage (E),
resistance (R) and the resultant current (I) in an
or I (current) equals E (voltage) over R
This means that the current in a circuit is directly
related to the voltage divided by the resistance. ie.
If the voltage stayed constant the current would
increase as the resistance decreased.
COLLOIDAL SILVER FACTS
High grade colloidal silver is produced from high
grade distilled water. (If it's not made from high
grade distilled water - don't drink it.)
High grade distilled water is very pure and as
such has a very, very high resistance (very low
Automatic conductivity sensing colloidal silver
generators turn off when the conductivity of the
water, ie. when the current through the water reaches
a certain level.
To produce a constant current at the
beginning of the process when the resistance through
the water is very, very high, the voltage applied would
also need to be very, very high. In actual fact,
probably 1000's of volts, but the "Constant Current"
generator producers claim that the generators are a low
voltage unit. ie. around 27 to 30 volts.
With a typical low voltage colloidal silver
generator, the current at the beginning of the process
will (should) always be very, very low. This current will
increase very slowly as the conductivity increases
(resistance decreases) due to the increase of silver
content in the water.
After a few hours (not minutes - NOTE: This depends on
the quantity of water being converted) the current will
have reached a point where the sensor will switch the
unit off, as it is designed to do. This switch off
current point controls the PPM (parts per million) strength of the colloidal
In actual fact, most colloidal silver generators are
more what could be termed "Constant Voltage". In nearly
every case the voltage would be constant for most of
the process and then reduce slightly, due to internal
resistance of the circuitry, as the generation process nears completion
and as the circuit goes into constant current mode.
Some colloidal silver generators which do not turn
off automatically by electronic sensing, will use a
constant current mode at the end of the process using a
current limiting system, so that the current cannot
exceed a certain amount. These generators often use a
timer (internal or external) to switch the unit off
after a predetermined time. This timer method produces
colloidal silver of an inaccurately determinable
strength. The temperature and other factors can effect
Maybe, some people who use the term "Constant
Current" refer to the fact that their generator puts
out a continuous current without it being interrupted.
That is not the true meaning of constant current.
Simple generators which use current limiting will
run continuously in constant current mode if water other than high
grade distilled water is used or run at constant
current at the end of the cycle as the silver
concentration builds up in the water.
