Understanding the Resistivity of Water

2020/12/29Whether you want to identify the electrical conductivity of a solution or are interested in learning how acidic or alkaline water is, there are many measurements that can be taken of water. One of these measurements centers around understanding the resistivity of water, which indicates the ability that the water has to effectively resist an electrical current .

What is Electrical Conductivity?

Electrical conductivity is a measurement of how easily a material allows electric current to flow through it. Inversely, electrical resistivity measures how strongly a material resists the flow of electric current. The two properties are exact inverses of each other.
