Can water decrease a substances's resistance to the flow of electricity?
A item's resistance is not able to be changed with water. Water on an object or absorbed by an object can change the overall resistance of an object by putting in parallel the resistance of the water itself. If you were to use very clean water that was deionized and soaked your device, you would see no resistance change.
How much current is need for 12 VDC to flow through water?
First thing voltage does not flow current does. Voltage is the potential or pressure needed to make the current flow. Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. To make the current flow you have to adjust the resistance of the circuit and that would be the water in this case. Salt added to water will make the water conductive so the resistance can be adjusted thereby making the current rise or fall depending on the water solution's resistive properties. The equation that you should consider using is Amps = Volts/Resistance.

What is the difference of voltage resistance and current as the apply to electric circuit?
E=IxR E- Electromotive Force, measured with voltage - volt - v. I- Current, measured with amperage - amp - a. R- Resistance measured with ohms - (Greek omega symbol) Voltage = pressure. Current = flow. Resistance = opposition to flow such as wire size or load. If electricity was water then the water pump is the voltage. The water flowing through the pipe is the current and the size of the pipe is the resistance. Smaller pipe more resistance.
Is electricity current?
I like to use a water tower connected to a pipe as an example of how electricity works. Electricity depends on voltage AND current. If you think of it like a water supply then the voltage would be like the pressure in the pipes due to the height of the water tower. The current would be like the speed with which the water flows through the pipes and that is determined by the resistance, which we can think of as the size of the pipe. If we make the pipe bigger, that is, decrease the resistance, then the water flows faster. If we decrease the resistance in an electrical circuit then the current increases. That is why you often hear the term current used for both electricity and water flow. For more technical details please see my answer to the question about resistance. "If a fuse will melt.."
What happens to the current if restistance is increased and why?
There is an electronic formula voltage/resistance = current If you translate this into plumbing terms voltage would equal water pressure resistance would equal pipes and valves and the current would equal the flow rate. If you start closing a valve it increases resistance and lowers the current flow
Why does current change when voltage is increased?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
Why are wires supplying electric current to the water heater thicker than those supplying current to the lights?
the water heater operates at high power compared to the lights and so the water heater requires a larger current. The wires supplying current to the water heater are thicker so that the wires have a low resistance. This reduces the risk of the wires overheating.
Why doesnt temperature change when transferring from ice too water?
The thermal energy required to change state is taken from the environment; which in this case is the melt water.
Which diode will work when two different diodes are in parallel?
the path of least Resistance electricity is like water it flows in the direction of least Resistance so current should flow in the diode with the lowest Resistance but if the draw on current was high enough it would also start to flow in the higher resistance diode
Why do you always speak about voltage drop and not current?
Voltage is like the pressure in your hose pipe. Current is the flow of charge and equivalent to the rate of flow of the water. Due to resistance to the water in the pipe,the pressure of the water will reduce along the length of the pipe but the quantity of litres flowing in the pipe will not change. So voltage will be maximum at the source of the voltage but as you move along the conductor there is voltage drop due to the resistance of the conductor.However, the current is same at all points along the conductor (the flow of charge is uniform at all points)
How does changing resistance affect voltage and current?
current change with resistance as, anything which opposes flow of current is called resistor is circuit, now we use battery to give potential across the circuit, potential just ensure the continuous flow of charge from higher to lower potential (water flows from high PE to low PE), while resistance opposes the flow of charge and thereby effecting the value of current, it's practically found that more is the resistance, less is the current flowing through resistance, this is indirectly observed from ohm law V=IR.
