7800 watt-hours.
3 days 6 hours.
3 days x 24 hours in a day = 72 hours
72 hours + 6 hours = 78 hours.
7800 watt-hours / 78 hours = 100 watts/hour
100 watts/hour x 24 hours = 2400 watts/day
just did that fast, might be wrong? :P
A light bulb consumes watt-hours per day. How many watt-hours does it consume in days and hours?
13500/3600= 3 days and 3/4 of a day
8400
2400
A 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.
There are many kinds of street lights some consume as much as 750 W others (newer LED varieties) as little as 30W or as much as 180 W. In 10 hours you would multiply these figures by 10.
Let us consider that Watts means Watt-hours per hour. So a battery charger that consumes 15 Watt-hours per hour will consume 15x24 Watt-hours per day. And at 0.06 dollars per 1000 Watt-hours the cost will be 15x24x0.06/1000 or just over two pennies per day.
It consumes (actually "converts") 1.5 kW every hour it is on, equivalent to about 2 horsepower-hours, meaning you'd need two horses pulling simultaneously if you were to want to run that bulb all day.
energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit
Your A/C or your dryer/washer , but if you leave your T.V on for >10 hours the T.V will consume more energy than your washer and dryer.
5 days 12 hours = 5.5 days19,800 / 5.5 = 3,600 watt-hours per day = 150 watts

Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.
Amps times volts = watts Watts measures the rate of power usage. watts times hours = watt hours Watt hours is a measure of the amount of power used.
800 watthours, = 0,8 kWH, over here about 10-20 eurocents I guess.

First let me define what is a KWh. If a machine consume 1000 watt and we use it for one hour it will consume one KWh, thousand watt consumption for one hour. An average Desktop Computer with 17 Inch CRT Monitor takes Roughly 300 watts means that continuous use of 3 hours consumes one KWh. If you are using a LCD Monitor then you can save lot of power. One KWh can run a Desktop for roughly 6 Hours.
not enough....
New York City consumes about 39.4 million kilowatt hours annually.
