Nichrome Resistance Calculator


Calculating the resistance of a Nichrome wire is crucial for various applications, such as heating elements and electronic devices. In this article, we’ll guide you through the process of creating a Nichrome Resistance Calculator using HTML and JavaScript. This interactive calculator will provide accurate resistance values based on user inputs.

How to Use

To use the Nichrome Resistance Calculator, follow these simple steps:

  1. Input the length of the Nichrome wire in meters.
  2. Enter the cross-sectional area of the wire in square millimeters.
  3. Specify the resistivity of Nichrome in ohm-meters (Ω·m).
  4. Click the “Calculate” button to obtain the resistance value.


The formula to calculate resistance (R) is given by:


  • is the resistance,
  • is the resistivity of Nichrome,
  • is the length of the wire, and
  • is the cross-sectional area of the wire.


Let’s consider an example:

  • Length = 2 meters
  • Cross-Sectional Area = 0.5 square millimeters
  • Resistivity of Nichrome = 1.10 × 10−6 ohm-meters


After solving, the calculated resistance will be displayed.
