How many watts do you need to run a 1.1 amp fridge?

Answer 1

Your refrigerator is an AC induction motor. It will draw constant current whenever it is on (after starting which is much higher). However the power that it consumes depends on the torque on the motor's shaft, which in the case of your refrigerator depends on the temperature difference between your freezer and the radiator coils on the back or bottom of the fridge. As time goes on, dust collects on these coils and power consumption goes up. The correct answer to this question is 'some fraction of 120 volts * 1.1 amps = 132 watts or less.' The rest of the 1.1 amps of current represents energy which is borrowed from the line and returned to it at a different time during the AC cycle. The ratio between current*voltage and actual power consumed is referred to as power factor. Some devices like lights and heaters have a power factor very close to 1 because they do not borrow power from the line. Induction motors and Transformers have power factors lower than 1.

Answer 2

To calculate the wattage needed to run a 1.1 amp fridge, you can use the formula: power (watts) = current (amps) x voltage (volts). Assuming the fridge operates on a standard 120-volt outlet, the calculation would be: 1.1 amps x 120 volts = 132 watts. Therefore, you would need 132 watts to run a 1.1 amp fridge.
