Depends on the primarily on the size and specific features, but should also be affected by settings, ambient temperature/how often it is opened (how hard it is going to have to work, age and maintenance.
E.g., Assuming normal operating conditions my Electrolux 11.5 cubic foot model consumes 109W/hr (which in my particular location costs me about $10 per month to operate).
Look at the label on the back of your specific refrigerator or in the owners manual that came with it.
The formula you are looking for is Watts = Amps x Volts.
There are zero watts in a small refrigerator. Watts are the produce to amps times volts. Without these values a correct answer can not be given.
Probably about 450 watts. Since the primary use of power in a refrigerator is for a motor the watts it uses are less than the amps that pass through it. <<>> Assuming that the refrigerator uses 120 volts for a supply voltage, then W = A x V. 4.5 x 120 = 540 watts
Kitchen refrigerators use 50-100 watts for about five minutes per hour, so 10 watts or less on average.
50 - 60 watts Mine uses 500 watts, but only for about two minutes each hour.
Depends on your type of refrigerator since different models use different amounts of electricity.
400 Kwh per year (1996 - 120 liters)
If it uses 60 watts at 115volts then it only uses 0.51amps.
On average, a Frigidaire or refrigerator uses around 600 watts. This is assuming that the fridge is an average to large size, and not a tiny fridge that would use less power.
Watts is determined by multiplying amps (found on tag with serial number or on data plate on compressor) by volts (example 115 volts times 9 amps= 1035 watts)
The equation to use to find wattage is W = A x V. Watts are equal to the amperage times the voltage. Look on the nameplate of the unit to find the true amperage and voltage needed to operate the refrigerator.
I estimated 1100 - 9AMPS -running, not sure what the surge startup would be.
