Amps to kVA Calculator Using JavaScript With HTML

Hello Friends Today, through this tutorial, I will tell you How to Create Amps to kVA Calculator Using JavaScript with HTML? Below is an example of an Amps to kVA calculator using JavaScript with HTML. Please note that the power factor is assumed to be 0.8 in this example, but you can adjust it based on your specific application.

<h2>Amps to kVA Calculator</h2>
<label for="amps">Enter Amperage (A):</label>
<input type="number" id="amps" placeholder="Enter amperage">
<button onclick="calculateKVA()">Calculate kVA</button>
<p id="result"></p>
function calculateKVA() {
// Get the amperage input value
const amps = parseFloat(document.getElementById('amps').value);
// Assumed power factor (adjust as needed)
const powerFactor = 0.8;
// Calculate apparent power (kVA)
const apparentPowerKVA = amps / 1000 / powerFactor;
// Display the result
document.getElementById('result').innerHTML = `Apparent Power (kVA): ${apparentPowerKVA.toFixed(3)} kVA`;

This HTML file includes an input field for entering amperage, a button to trigger the calculation, and a result paragraph to display the calculated apparent power in kilovolt-amperes (kVA). Adjust the power factor based on your specific application. When the button is clicked, the `calculateKVA` function is called, which performs the calculation and updates the result on the page.
