" To measure *current* you actually have to interrupt your circuit and

arrangement as for measuring the voltage."
If the system is arranged in this way it will be inevitable that at some
time the two electrodes will touch together and the fuse of the meter will
be blown. It is best to use a resister of a fixed value that will limit the
current to a Max level. If we use four nine volt batteries we have a total
of thirty six volts. If we deduct the minimum voltage differential of our
colloidal silver generators cell of four volts that leaves us with thirty
two volts. Here is a setup using a 37K resister with the multimeter set on
voltage measurement across the resister. As the process of generating ions
progresses and the resistance of the cell decreases the voltage across the
resister will simply increase. If the electrodes are accidentally shorted
together, no harm will be done. The current will be limited to one milliamp
in this case at the available voltage of thirty six volts, divided by the
resistance thirty three thousand Ohm's, resulting in a current of one
milliamp, approximately. I have included some JPEGs is to illustrate this.
The resister with little loops already formed at each end. Put the probes
from the multimeter inside the loops. Here is the picture.

Attach an alligator clip from one of the jumper cables to one of the test
leads tip points as shown. Do the same again with another test lead.
Attach an alligator clip from the unused jumper cable to one of the battery
terminals that is still exposed. The other end of this cable clip onto the
end of one of the lengths of silver wire.

You are almost there. Remember the two jumper cables that you attached to
the resister and test probes? Choose one of those and attach the free and
to the remaining battery terminal that is still exposed.
Attach the free and of the remaining cable to the other piece of silver as
shown.
Now we are ready to test our generator. Turned the control on the
multimeter to two hundred volts DC as shown in the picture. When the two
silver wires are separated it should read zero volts.

When you touch the two silver wires together, this causes the voltage to
flow through the resister and a major will read approximately thirty eight
volts, which happens with fresh batteries.

Great news, Kathryn! <GRIN>
Now, just remember, for voltage readings the probes need to be
connected across the voltage source you want to measure. Very little
current will flow through the meter in voltage reading mode.
To measure *current* you actually have to interrupt your circuit and
let the current flow *through* the meter. It's not the same connection
arrangement as for measuring the voltage. Hook it up right, and you'll
never blow that fuse again!
Current is more useful to know than voltage, so you'll probably leave
it wired up that way most of the time.
Be well,
Mike D.
