# Coax Cable Calculator Impedance Inductance Capacitance

Introduction

Calculating the impedance, inductance, and capacitance of coaxial cables is essential in various electronic applications. Whether you’re an engineer, hobbyist, or student, understanding these parameters is crucial for designing efficient circuits and systems. In this article, we’ll delve into the process of using a coax cable calculator to determine these values accurately.

## How to Use

To utilize the coax cable calculator effectively, follow these steps:

- Input the required parameters such as the cable’s dimensions, dielectric constant, and frequency.
- Click on the “Calculate” button to obtain the impedance, inductance, and capacitance values.
- Analyze the results to make informed decisions regarding your electronic design.

## Formula

The calculation of coaxial cable parameters involves several intricate formulas. One of the fundamental formulas used is:

Where:

*Z*is the impedance.*R*is the resistance per unit length.*L*is the inductance per unit length.*G*is the conductance per unit length.*C*is the capacitance per unit length.*ω*is the angular frequency.

## Example Solve

Let’s consider an example where we have a coaxial cable with the following parameters:

- Resistance per unit length (
*R*): 0.1 ohms/m - Inductance per unit length (
*L*): 0.2 μH/m - Conductance per unit length (
*G*): 0.01 S/m - Capacitance per unit length (
*C*): 50 pF/m - Operating frequency (
*f*): 1 GHz

By plugging these values into the formula, we can calculate the impedance of the coaxial cable.

Upon computation, we find the impedance to be approximately *Z*=16.38+*j*5.53 ohms.
