The number of watts measures the power, and Ohm's laws requires us to know the current as well as the voltage to determine the power.
P = i x e
For example, if the fridge draws 10 amps at 115 volts, the power is 1150 watts.
Answer
The answer is that it depends on the fridge. Look at the nameplate information for your particular fridge; that's where you will find your answer.
Watts and Volts are two distinct types of measurement.
1 watt = 1 amp * 1 volt So.... In a house: 5 amps * 115 volts = 575 watts In a car: 5 amps * 12 volts = 60 watts
Ohms law will tell you watts equals volts times amps: 115 x 5 = 575
There are 115 of them.
3% of 115 = 115*3/100 = 3.45
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
There are normally at least 115 watts per fridge.
A typical 15-amp, 115-volt residential outlet can handle up to 1,725 watts (115 volts * 15 amps). However, it's recommended to leave some margin and avoid continuously drawing the full capacity to prevent circuit overloading.
Watts is found by multiplying the volts by the amps. Normally a supply is provided at a fixed voltage, and the amount of current that is drawn depends on how many watts the equpiment requires.
Divide the watts by the volts, so 32 / 115 is the answer in amps.
978 watts
You need to know how many amps not hertz! use ohms law. 115 volts x 10 amps (example) = 1150 watts. volts x amps = watts So uf tou have a 10 amp 115 fridge you need at least a 1200 watt invertor, BUT WAIT. you need more than that to start the compressor at least 50 percent. So an 1800 to 2000 watt invertor will do for this fridge. But now you have to have enough reserve capacity in your battery. This will require more than one battery or a constant charge.
Watts and Volts are two distinct types of measurement.
To calculate the amps for 115 watts, you need to know the voltage the appliance is operating at. If the appliance is operating at 120 volts, then the current would be approximately 0.96 amps (115 watts / 120 volts).
To calculate the amperage, use the formula: Amperes = Watts / Volts. For this situation, it would be 4000 watts / 115 volts ≈ 34.78 amps.
In U.S. voltage is usually referred to as 120 nowadays. so if in U.S. substitute 120 where 115 appears below. Power = Amperage times voltage So, in your example, 8.5 times 115 = Watts
