A refrigerator is an essential appliance that is commonly found in every household. It helps keep food and drinks fresh, and it’s important to know how much electricity it consumes to keep your energy bills in check. In this article, we will discuss the power consumption of an 18 cu ft refrigerator and how to calculate its energy usage.

Understanding Amps and Watts

Before discussing the power consumption of an 18 cu ft refrigerator, it’s essential to understand the terms “amps” and “watts.” Amps (A) are the unit used to measure the flow of electric current, while watts (W) are the unit used to measure the rate at which electricity is consumed or produced.

Power Consumption of an 18 cu ft Refrigerator

The power consumption of an 18 cu ft refrigerator can vary depending on various factors such as the age of the appliance, its efficiency, and the frequency of use. On average, an 18 cu ft refrigerator uses between 100 and 200 watts of electricity when running.

Calculating Energy Usage

To calculate the energy usage of an 18 cu ft refrigerator, you need to multiply the appliance’s wattage by the number of hours it runs each day. For example, if your refrigerator uses 150 watts and runs for 10 hours a day, it would consume 1.5 kWh of energy per day. Multiply this by the number of days in a month to determine the appliance’s monthly energy consumption.
