Water can decrease a substance'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.

What happens to electrical in a resistor?
when you think of electricity and resistance think of it as water in a river and rocks in a river. The water being the electricity and the rocks being the resistance. when water in a river flows and then come across rocks that block the water from flowing constantly, it slows down the water. therefore when electricity is flowing through a circuit with resistance, when it hits the resistors it slows the flow of electricity.
The presence of these in water causes water to conduct electicity?
Pure water, by itself, is not capable of conducting electricity. However, when other substances are added and ions make their way into water, those free ions can cause water to conduct electricity.
The flow of electricity can be compared to the circulation of water in a?
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
Why does resistance of human body decrease to electricity when body is wet?
If you increase resistance, current is restricted (river is damed up). If you decrease restistance, current flows faster (river is wide and open). With water on our skin the current can travel across our skin instead of having to move through our bodies. The current has found a new path. Not inside our bodies but outside our bodies where there is much less resistance. Which is better? A large highway with a traffic jam or the side road next to the highway with the traffice jam The side road is effected by the traffic jam, but is still faster than the highway.
What is the difference between neutral earthing resistance and solid earth?
The star point of a primary*-transformer's secondary winding is frequently connected to earth via an impedance, in order to limit the return current in the event of an earth fault close to the transformer. The impedance may be a resistor or an inductor, (choke) depending on the nature of the earth return. In general, if the earth resistance is low, then resistive earthing is used; if the earth resistance is high, then inductive earthing is used.(*e.g. 33/11 kV)For resistive earthing, the transformer secondary's star point is often connected to the centre electrode of a galvanized-steel tank which is solidly earthed. The tank is then filled with water, and it is the resistance of the water that provides the required resistance to earth. The actual resistance of the water is modified to the desired value by dissolving sodium carbonate into the water while measuring its resistance. The solution has a negative temperature coefficient of resistance, which means that, in the event of an earth fault, as the fault current increases, the increasing temperature causes the resistance of the water to decrease, thus accelerating the response time of the protective system.

no

Can Water can decrease a substance resistance to the flow of electricity?
Reduce the temperature of the conductor.
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.."

Is a water a conductor or an insulator of electricity?
Pure water, that is to say without any other substances, actually does not conduct electricity. Water with impurities, on the other hand, does conduct electricity. Since water is usually impure, common water conducts electricity.
Do simple molecular substances conduct electricity?
Most molecular substances do not conduct electricity since the ions don't dissociate very well with molecular substances. However, most ionic substances do conduct electricity very well due to their ability to dissociate very well in water.
What is the link between water that contains other substance and is ability to conduct electricity?
pure water does not conduct electricity. the presence of electrolytes in the water is what conducts electricity. the equation for the conductivity (ability to conduct electricity) Conductance = 1/ resistance
Water can decrease a substance's resistance to the flow of electricity is this true?
Yes this is true. Unless it is pure distilled water, water is conductive. This is due to the amount of mineral content that is dissolved in the water. If you were to receive a shock while standing in water, it would be much more sever that when standing on a dry surface.
Do substances which dissolve in water conduct an electric current?
Some do. Electrolytes, which are substances that break into ions when dissolved in water, will conduct electricity. Such substances include soluble salts, acids, and bases.Other water soluble substances are non electrolytes and do not break into ions in water, or at least do so in extremely minute amounts. They do not conduct electricity. These include alcohols, sugars, and some other polar compounds.
What path electricity flow through?
like water it follows the path of least resistance
