1. What is a Power Consumption Calculator for India?

Definition: This calculator estimates the energy consumption in kilowatt-hours (kWh) based on appliance power rating and usage time.

Purpose: It helps Indian households and businesses estimate electricity usage and costs for better energy management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kilowatt-hours)
• \( P \) — Power rating of appliance (watts)
• \( t \) — Time of usage (hours)

Explanation: The formula converts watt-hours to kilowatt-hours (kWh) by dividing by 1000, which is the standard billing unit in India.

3. Importance of Power Consumption Calculation

Details: Accurate energy calculation helps in budgeting electricity costs, comparing appliance efficiency, and reducing carbon footprint.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and usage time in hours. Common ratings: LED bulb (9W), fan (50W), AC (1500W).

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power rating?
A: Check the nameplate, manual, or specifications. 1W = 1J/s. Most appliances list their power consumption.

Q2: Why divide by 1000?
A: Indian electricity bills charge per kilowatt-hour (kWh), which equals 1000 watt-hours.

Q3: How can I estimate monthly consumption?
A: Multiply daily kWh by 30. For seasonal appliances, adjust usage days accordingly.

Q4: What's the average Indian household consumption?
A: Typically 200-300 kWh/month, but varies by region, appliances, and family size.

Q5: Does this account for power factor?
A: This simple calculator assumes unity power factor. For precise industrial calculations, include power factor.
