Conductivity in Metals Solution

STEP 0: Pre-Calculation Summary

Formula Used

Conductivity = Electron Concentration*[Charge-e]*Mobility of Electron
σ = N_e*[Charge-e]*μ_n
This formula uses 1 Constants, 3 Variables

Constants Used

[Charge-e] - Charge of electron Value Taken As 1.60217662E-19

Variables Used

Conductivity - (Measured in Siemens per Meter) - Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. It is the reciprocal of resistivity.
Electron Concentration - (Measured in 1 per Cubic Meter) - Electron Concentration is defined as the concentration of electrons with respect to the volume.
Mobility of Electron - (Measured in Square Meter per Volt per Second) - Mobility of electron is defined as the magnitude of average drift velocity per unit electric field.

STEP 1: Convert Input(s) to Base Unit

Electron Concentration: 3E+16 1 per Cubic Meter --> 3E+16 1 per Cubic Meter No Conversion Required
Mobility of Electron: 180 Square Meter per Volt per Second --> 180 Square Meter per Volt per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ = N_e*[Charge-e]*μ_n --> 3E+16*[Charge-e]*180

Evaluating ... ...

What is electrical conductivity in metals?

Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.

Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal. Under an electric field, free electrons move through the metal much like billiard balls knocking against each other, passing an electric charge as they move.

How to Calculate Conductivity in Metals?

Conductivity in Metals calculator uses Conductivity = Electron Concentration*[Charge-e]*Mobility of Electron to calculate the Conductivity, Conductivity in metals refers to the material's ability to conduct electric current. It is a fundamental property of metals and is a result of the presence of free electrons that can move easily throughout the material. Conductivity is denoted by σ symbol.
