I have some waterproof electrical components that will be powered by a dc power supply. The voltage will be from 12 to 35 v. The power supply will be away from the water but there will be two power terminals under water that cannot be insulated. The terminals are locate 4 to 5 feet apart from each other. If the sum of the current from the electrical components and the current across the terminals from the water is less than the rated current on the power supply, will the circuit function properly? Is there a way to calculate the current through the water as a function of distance and voltage? This will not be salt water.
