Hi Jim, You are confusing voltage and current (amperage). You can increase DC voltage without a problem. This will lower the available amperage, but for making CS that isn't a problem. Your friend is right, a resistor will limit the current in the circuit, but it isn't really necessary, since you shut off when the current gets to 2-3ma @ 30volts. The current will start much lower, around .2-.4mA using only good distilled water. If your starting current is higher than that, get your water from somewhere else.
Your voltage will remain constant throughout the process. As the solution gains more silver in the water, the resistance of the water will steadily drop, allowing more current to pass thru the water. You simply clip one end of your multimeter to one side of the generator, and the other end of your multimeter to one of the silver wires. Set it to read mA and watch the meter. Make sure you pay close attention to the polarity of the meter when you connect it, or you can blow out the meter. See the instruction manual for how to read amperage with your digital meter. Hope that helps Jim. The setup above is only good for people using constant voltage generators (3x 9volt or a power supply). If you are using a current regulated generator, you need to figure out what voltage to shut off at instead, since it is another variable in the equation. You can do that by clipping a 15Kohm 1/2 watt resistor in place of your silver wires, and then measuring the voltage at the clips. This will give you the voltage you want to shut off at. When your voltage drops to the value you just measured, shut off your generator. Simple. This method will give you a highly repeatable grade of CS. If you don't care about that, don't worry, what you are doing is probably working just great for you.

Put your digital ammeter in series, using 10.3 volts, turn off the generator at 686 uA which should be approximately 10ppm. If you want 5ppm turn it off at 515 uA. When you go to 31volts turn it off at 2.06mA for 10ppm or 1.55mA for 5ppm. This is the same as 15000 or 20000 ohms total resistance for both voltages. Current regulation is really un-necessary since you should never allow the current to go above 2-3mA (@ 30 volts) with high quality distilled water. Of course there is lots of room for advanced experimentation. See some of Bob Lee's recent posts for truly advanced techniques in the highest form of the CS art. Bless you, Bob Lee. The figures above use a 2" to 2 1/4" spacing on your electrodes with about 3 1/2" wetted 14ga silver wire and 16oz of room temperature water. Adding a fish tank bubble stone or small stirring motor or hand stirring makes a lot of difference in the quality of the CS, but have fun, it all works well!
