Question

what do you understand by the resistivity of a substance​

Answer 1

Explanation:

Resistivity definition:

The resistivity of a substance is the resistance of a cube of that substance having edges of unit length, with the understanding that the current flows normal to opposite faces and is distributed uniformly over them. ... The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m).

Resistivity means resist to change,in simple words power to oppose anything here we talk about electricity.

The resistivity of a substance means is a characteristic of a substance by which we can know the electrical property of a substance.

➜If a substance having low resistivity then it allows maximum electric current to pass through them means it opppose less.

➜If a substance having high resistivity then it allows minimum electric current to pass through it means it oppose more.
