Understanding your refrigerator’s amperage is vital for calculating energy consumption and costs over time. The formula to calculate energy consumption in kilowatt-hours (kWh) is simple:
Energy Consumption (kWh) = (Voltage x Amperage x Time in hours) / 1000
Example Calculation
Let’s say you have a refrigerator that operates at 120 volts and 5 amps, and it runs for 24 hours:
- Energy Consumption = (120V x 5A x 24 hours) / 1000 = 14.4 kWh
If your electricity rate is $0.12 per kWh, your daily cost to run the refrigerator would be:
- Cost = 14.4 kWh x $0.12 = $1.73 per day.
This calculation highlights that knowing the amperage can assist you in budget planning, empowering you to make informed decisions.
