The total conductivity is illustrated by the image below.

To compute for total conductivity, two essential parameters are needed and these parameters are **Electronic Conductivity (σ _{electronic})** and

**Ionic Conductivity (σ**

_{ionic}).The formula for calculating total conductivity:

Where:

σ_{total} = Total Conductivity

σ_{electronic} = Electronic Conductivity

σ_{ionic} = Ionic Conductivity

Let’s solve an example;

Find the total conductivity when the electronic conductivity is 32 and the ionic conductivity is 8.

This implies that;

σ_{electronic} = Electronic Conductivity = 32

σ_{ionic} = Ionic Conductivity = 8

σ_{total} = σ_{electronic} + σ_{ionic}

σ_{total} = 32 + 8

σ_{total} = 40

Therefore, the **total conductivity **is **40 S/m.**

**Calculating the Electronic Conductivity when the Total Conductivity and the Ionic Conductivity is Given.**

σ_{electronic} = σ_{total} – σ_{ionic}

Where:

σ_{electronic} = Electronic Conductivity

σ_{total} = Total Conductivity

σ_{ionic} = Ionic Conductivity

Given an example;

Find the electronic conductivity when the total conductivity is 18 and the ionic conductivity is 9.

This implies that;

σ_{total} = Total Conductivity = 18

σ_{ionic} = Ionic Conductivity = 9

σ_{electronic} = σ_{total} – σ_{ionic}

σ_{electronic} = 18 – 9

σ_{electronic} = 9

Therefore, the **electronic conductivity **is **9.**

**Calculating the Ionic Conductivity when the Total Conductivity and the Electronic Conductivity is Given.**

σ_{ionic} = σ_{total} – σ_{electronic}

Where:

σ_{ionic} = Ionic Conductivity

σ_{total} = Total Conductivity

σ_{electronic} = Electronic Conductivity

Let’s solve an example;

Given that, the total conductivity is 8 and the electronic conductivity is 3. Find the ionic conductivity?

This implies that;

σ_{total} = Total Conductivity = 8

σ_{electronic} = Electronic Conductivity = 3

σ_{ionic} = σ_{total} – σ_{electronic}

σ_{ionic} = 8 – 3

σ_{ionic} = 5

Therefore, the **ionic conductivity **is **5.**
