How many amps does a 1500 watt amp draw?
Using the W ÷ V = A variation of Ohm’s law, you can calculate that 1,500 watts ÷ 120 volts = 12.5 amps.
How many amps does a refrigerator draw?
A typical refrigerator draws 725 watts, according to the United States Department of Energy. Divide that number by 120 volts, which is the voltage of your power supply, to get the current that the refrigerator draws in amperes. A 725-watt refrigerator draws 725/120 = 6 amps.
How much power does a refrigerator draw?
Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh). This translates into a running cost of about $150 per year per fridge.
How much power does a fridge draw?
The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it. Different types of fridges have different power requirements.
How many amps does 55 watts draw?
