Reduce the temperature of the conductor.
Water
magnetism, gravity, friction, electricity, contact, non contact, tension, air resistance, water resistance, upthrust and spring force
Earth can conduct electricity but not as good a wires. Its resistance depends on the kind of the ground , how far is one point from the other where you measure the resistance, the moisture, and other factors. So, i think it's a conductor _________________________________________________________________________ Strange question.... Since the surface of the earth is mostly covered in water and water is a good conductor of electricity I'd say it's a conductor.
no
Reduce the temperature of the conductor.
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.
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

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.
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.."
Air resistance is that resistance when substance moves in air and it expresses a opposite force on it. However, water restinace is water when a substance moves thorugh water and it expresses and oppoisite force.
electricity I think
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.
No. A substance that does not contain ions will not be a conductor of electricity.
No.
