1. What is Electricity Consumption?

Electricity consumption measures how much electrical energy a device uses over time, typically measured in kilowatt-hours (kWh). It's essential for understanding energy usage and calculating electricity costs.

2. How Does the Calculator Work?

The calculator uses the electricity consumption formula:

Where:

• \( kWh \) — Kilowatt-hours (energy consumption)
• \( P \) — Power consumption in watts (W)
• \( h \) — Time in hours
• 1000 — Conversion factor from watts to kilowatts

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000, since 1 kilowatt equals 1000 watts.

3. Importance of kWh Calculation

Details: Calculating kWh helps estimate energy costs, compare appliance efficiency, and understand your electricity bill. It's crucial for energy conservation and budgeting.

4. Using the Calculator

Tips: Enter the device's power rating in watts and the duration of use in hours. For accurate results, use the actual power consumption (not just the device's maximum rating).

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power consumption?
A: Check the label or manual for wattage (W). Alternatively, use a wattmeter for precise measurement.

Q2: How can I estimate monthly consumption?
A: Calculate daily kWh, then multiply by number of days in the month. For example: (kWh per use) × (uses per day) × 30.

Q3: What's the average kWh consumption for common appliances?
A: Refrigerator: 1-2 kWh/day, LED TV: 0.05-0.2 kWh/hour, Laptop: 0.02-0.05 kWh/hour, Incandescent bulb: 0.06 kWh/hour.

Q4: How does this relate to my electricity bill?
A: Multiply kWh by your electricity rate (per kWh) to estimate cost. For example: 10 kWh × $0.15/kWh = $1.50.

Q5: What's more accurate - watts or amps?
A: Watts are more direct for this calculation. If you have amps (A), multiply by voltage (V) to get watts: W = A × V.
