Resistivity is a fundamental property in the field of electrical physics. It characterizes how materials resist the flow of electric current. In this brief article, we will define resistivity and learn its SI unit, shedding light on its importance.

SI Unit of Resistivity

The SI unit of resistivity is the ohm-meter (Ω·m). This unit combines the ohm (Ω), which represents electrical resistance, with the meter (m), which signifies the length of the material in question.

It quantifies how strongly a given material opposes the flow of electric current. Materials with higher resistivity impede the flow of current more than those with lower resistivity.
