9 Best Free Online Resistivity Calculator Websites

Here is a list of the best free online resistivity calculator websites. Resistivity is a measure of the resisting power of a material to the flow of an electric current. In simple words, it implies the efficiency of material for the flow of electric charge. Resistivity is used to determine the conducting ability of a material. If the material has high resistivity, it conducts less current and can be called a bad conductor.

To be able to know the resistivity of a material (say wire), you should know the resistivity of the wire. You can look that up on the wire or online. Along with the resistance, you should know the length and cross-section area of the wire. With these three values, you can calculate the resistivity of the wire.
