The multiple of (0.5 kw per hour) X (total hours of functioning) X (the cost of 1kw-hr).
To convert watts to kilowatts, you divide by 1,000. Therefore, 500 watts is equal to 0.5 kilowatts. To convert minutes to hours, you divide by 60. So, 500 watts per minute is equivalent to 0.5 kilowatts per 60 minutes, or 0.5/60 = 0.00833 kilowatts per hour.
It doesn't. An ordinary kitchen refrigerator does not use much energy. Mine uses 500 watts for about 2 minutes per hour, an average of 17 watts.
Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts. It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1
Multiply the watts by the seconds: 500 x 300 = 150,000 Joules is the answer.

There are normally at least 115 watts per fridge.
Each refrigerator manufacturer has a different wattage. Look on the back of the unit and that information will be readily available.It depends on the size but my average kitchen fridge uses 500 watts for about 2 minutes per hour.
1 kilowatts = 1,000 watts 500kw=500,000w
The work done is equal to the power multiplied by the time. In this case, 500 watts × 2 minutes = 1000 joules.
It has over 500- 1000 watts
100 watt
The Signature Classics 8 cup model sold by Walgreens uses 500 watts.
