Several factors influence water resistivity. Some of the most important are 1) the concentration of ions in the water; 2) the mobility of the ions in the water (smaller ionic radius ions tend to decrease water resistivity more than larger ionic radius ions); 3) the oxidation state of the ions; and 4) the temperature of the water.

Why resistivity method is suitable for ground water exploration?
rain and flooding
What is the resistivity of graphite?
The resistivity of graphite is 7.837 µΩm.
What is thermal resistivity of soils?
Resistivity is the opposite of conductivity. The thermal resistivity of soil is the degree to which soil impedes the flow of heat, or insulates against heat.
What is electrical resistivity of molybdenum?
5.34E-8
Applications of resistivity method for groundwater?
Electrical resistivity method is an excellent tool for groundwater exploration.Current is injected in ground through two electrodes and resultant potential is measured through another pair of electrodes. These electrode are placed on ground at predefined locations .Wenner and Schlumberger are the most widely used configuration for placing the electrodes.Sounding with Schlumberger configuration is carried out for groundwater investigation.The data is then interpreted with available software and the results are in the form of resistivity and the thickness of different layers.These can be gainfully correalated with available geological data and thus site for dugwell/tubewell can be finalised.The sea water intrusion,factories polluting discharge also can be successfully delineated with resistivity method
Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
Is resistivity depends upon dimension of conductor?
no its depends on material properties.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
Why pure water is considered as insulator?
Yes! Pure distilled water is an insulator. it is the minerals, alkali's and acids in the contaminates that determine the resistivity of water!
Is resistivity of a material depends upon the dimensions of a material?
No. Resistivity is a property of the material itself and does not change no matter how much of that material you have. Resistance, however, does depend on the dimensions of the material.
Why resistivity method is suitable for ground water exploration?
rain and flooding
How would you describe the magnetic field produced by a current in a straight wire?
Yes. It depends on its resistivity
How does resistivity depends on temperature of conductors?
The resistance of a simple conductor normally rises as its temperature rises.
What is fresh and saline water resistivity?
the P.H. value of fresh water is 7 & the P.H. value of saline water is less than 7.
What has the author William R Eberle written?
William R. Eberle has written: 'The effects of water content and water resistivity on the dispersion of resistivity and dielectric constant in quartz sand in the frequency range 10' -- subject(s): Soil moisture, Electric resistance
What is the resistivity of graphite?
The resistivity of graphite is 7.837 µΩm.
