Inductance Per Unit Length Calculator

Introduction

Inductance is a fundamental property of electrical circuits, and it is particularly relevant in the design of transmission lines, antennas, and other electromagnetic components. The concept of inductance per unit length is valuable for quantifying how inductance varies along a conductor’s length and is crucial for understanding and optimizing electromagnetic systems.

Formula:

The inductance per unit length ( $L$ ) of a conductor is determined by the relationship between the inductance ( $L$ ) and the length of the conductor ( $l$ ). The formula for calculating inductance per unit length is given by:

L = l L

Where:

$L$ represents the inductance of the conductor.
$l$ is the length of the conductor.

How to Use?

Using the Inductance Per Unit Length Calculator involves the following steps:

Input Inductance ( $L$ ): Enter the value for the inductance of the conductor, typically measured in henrys (H).
Input Length ( $l$ ): Specify the length of the conductor for which you want to calculate the inductance per unit length, often measured in meters (m).
Calculate Inductance Per Unit Length ( $L / l$ ): Utilize the calculator to determine the inductance per unit length by applying the provided formula.

Example:

Let’s illustrate the calculation of inductance per unit length with a practical example:

Suppose you have a straight conductor with an inductance of 0.1 henrys (H) over a length of 2 meters (m). Calculate the inductance per unit length ( $L / l$ ) for this conductor.

Using the formula:

H = 0.05 H/m

So, the inductance per unit ( $L / l$ ) for this conductor is 0.05 henrys per meter (H/m).
