What is the Energy Calculator?

The Energy Calculator helps users determine the amount of energy consumed by an electrical device based on its power rating and the time it is used. By entering the power in watts and the duration in seconds, the tool calculates energy in joules and also converts it into kilowatt-hours (kWh). This allows users to understand power usage more clearly and estimate energy consumption for appliances, experiments, and daily electrical usage.

How to Use:

1. Enter Power (P): Type the device’s power rating in watts (W).
2. Enter Time (t): Provide the total time the device operates in seconds (s).
3. Click “Calculate”: The tool computes energy in joules and kWh using the formula E = P × t.
4. Review Result: The output shows energy in joules, energy in kilowatt-hours, the input values, and the formula used for calculation.
