All of the information is on the nameplate that is located, probably on the back of the fridge. Pull the unit away from the wall and look for the voltage and amperage that is stamped on the plate. Using the equation Watts = Amps x Volts, the wattage of the fridge can be found.
Divide Watts by Volts ; this gives you Amps.
To calculate the watts used by the refrigerator, multiply the amperage by the voltage. Assuming a standard household voltage of 120V, a 4.5 amp refrigerator would use approximately 540 watts (4.5 A * 120 V = 540 W).
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.

To convert amperage to watts, you need to know the voltage, power factor, and the number of phases that you are working with. For a residential refrigerator this is single phase, an industrial refrigerator could be three phase.
To calculate the wattage used by a 1.3 amp refrigerator in a month, you first need to determine its wattage. Using the formula: Watts = Amps × Volts, and assuming the refrigerator operates at 120 volts, it would use approximately 156 watts (1.3 A × 120 V). If the refrigerator runs 24 hours a day, it would consume about 112.32 kWh in a month (156 watts × 24 hours × 30 days ÷ 1000).
To calculate the amperage, use the formula: Amperes = Watts / Volts. For this situation, it would be 4000 watts / 115 volts ≈ 34.78 amps.
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
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
To calculate the current in amps from power in watts and voltage, you can use the formula: Amps = Watts / Volts. Therefore, for 200 watts at 240 volts, the calculation would be 200 watts / 240 volts = 0.8333 amps. So, 200 watts is approximately 0.83 amps at 240 volts.
A compact refrigerator typically uses around 50-100 watts when running. The exact wattage can vary depending on the size and efficiency of the refrigerator.
To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, it would be 70 watts / 13.8 volts ≈ 5.07 amps. So, with 70 watts and a voltage of 13.8 volts DC, the amperage would be approximately 5.07 amps.
