# How to Calculate and Solve for Static Sensitivity | First Order Instruments | Dynamic Characteristics of Instruments

**Last Updated on April 23, 2024**

The image above represents static sensitivity. Two essential parameters are needed to calculate static sensitivity: co-efficient (bo) and co-efficient** (a _{o}).**

**The formula for calculating static sensitivity:**

k = ^{bo} / _{ao}

Where:

k = Static Sensitivity

b_{o} = Co-efficient

a_{o} = Co-efficient

Let’s solve an example;

Find the static sensitivity when the co-efficient is 22 and the co-efficient is 11.

This implies that;

b_{o} = Co-efficient = 22

a_{o} = Co-efficient = 11

k = ^{bo} / _{ao}

So, k = ^{22} / _{11}

k = 2

Therefore, the **static sensitivity **is **2.**

**Calculating for Co-efficient when the Static Sensitivity and the Co-efficient are Given**

b_{o} = k x a_{o}

Where;

b_{o} = Co-efficient

k = Static Sensitivity

a_{o} = Co-efficient

Let’s solve an example;

Find the co-efficient when the static sensitivity is 21 and the co-efficient is 4.

This implies that;

k = Static Sensitivity = 21

a_{o} = Co-efficient = 4

b_{o} = k x a_{o}

Then, b_{o} = 21 x 4

b_{o} = 84

Therefore, the **co-efficient **is **84.**

**Calculating for Co-efficient when the Static Sensitivity and the Co-efficient are Given**

a_{o} = ^{bo} / _{k}

Where;

a_{o} = Co-efficient

k = Static Sensitivity

b_{o} = Co-efficient

Let’s solve an example;

Find the co-efficient when the static sensitivity is 10 and the co-efficient is 30.

This implies that;

k = Static Sensitivity = 10

b_{o} = Co-efficient = 30

a_{o} = ^{bo} / _{k}

So, a_{o} = ^{30} / _{10}

a_{o} = 3

Therefore, the **co-efficient **is **3.**
