Ok first off I'm a complete electronics novice so please take that into account when/if offering advice/answers please lol. Now my issue is that I'm trying build 2 colloidal silver makers, one that's 30VDC and one that's 30VAC. I have the two electrical adapters to achieve these two voltages but I need to keep the current at 1mA while the adapters are connected to two silver rods in distilled water. The resistance of the water will gradually decrease as more silver particles are added to the water so I ass u me I will need a variable resistor...? If this is correct then here are my questions: What values would the variable resistor be that I need for this application? Could I use the same resistor for both the AC and the DC circuit or would I need two different resistors? How would I connect the resistor(s) into the circuit(s)? And how can I test the circuit to make sure it's working properly? Any help with this would be greatly appreciated. Thank you. |

It seems that a constant current circuit (of 1mA) is what you look for. There are many circuits to accomplish this, check for those on the web and try it on the simulator here. |
