Concept explainers

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.

Question

**Characteristics of a Normal Conductor**

A normal conductor has the following characteristics:

- **Resistivity at 20°C (\( \rho_0 \))**: \( 7.21 \times 10^{-8} \, \Omega \cdot m \)

**Problem Statement**

What is the resistivity of this conductor at a temperature \( T = -33°C \)? Calculate the answer as a multiple of \( 10^{-8} \, \Omega \cdot m \) rounded off to 2 decimal places but do not include the unit.
