How many amps are needed to efficiently run a refrigerator?
If you are talking about a certain kind or brand, look at the label inside the door. The label will tell you how many amps this unit will need. However all residential refrigerators will run on a 15 amp dedicated circuit or be fine plugged into a regular 20 amp appliance circuit (which is required in kitchens). I have a large side by side unit and it only draws 6.6 amps max. Note that the starting current of an induction motor will be higher, of course, but will drop and stabilize at a "nominal" level within seconds.

For a 120 volt (V), 60 Hz system: 120 times about 7.5 amps (A) = 900 volt-amps (VA)
depends greatly on size usually assessed in tonnage how old the unit is and more
Watts Divided by 115 = AMPS
It should be on a 20 amp breaker.
I am not sure what you mean, but I think I have an Idea.. I would run four amps for surround sound since it would take up four corners. , by amps I take it you mean speakers…,
Check the nameplate or in themanual for the rating of the dishwasher. If you don't have the dishwasher manual, "Google" the make and model to get the specs. Usually appliance …feeds are on separate circuits out of the house panel. Mine is fed with a single pole 15 amp breaker. Unless it is a very big machine (industrial) it will be under 12 amps.
The wattage and the voltage are required for this. Divide watts by volts this will give you the amperage
amps equals watts divided by volts.
Minimal 100. Depends on load draw of home. Can be 200 amps or 400amps as well.
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 o…n 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.
It depends on the power of the oven, so you'd need to know that first. Then the current = (power in Watts) / Voltage.
Almost any average size home today will requre a 200 amp servicepanel.
Depends on your light usually it's a 60 wat balb
The formula for amperage is I = W/E. Amps = Watts/Volts. As you can see there are two values missing from the question.
