Using 100 watts for 2 hours consumes a total of 200 watt-hours, while using 50 watts for 4 hours consumes the same 200 watt-hours. The difference lies in the power output over time: the 100-watt appliance will consume power more quickly compared to the 50-watt appliance, but they both consume the same total energy.

How many hours is there in 200 watts?
200 watts is a unit of power, not time, so it does not directly correspond to a number of hours. Power is a measure of how fast energy is used or produced. To determine the energy consumed in watts per hour, you would need to know the duration of time the power is being used.
8 watts for 30 minutes is how many kilowatt hours?
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
What is the cost of using a 100 watts 220 volts lamp for twenty hours at three pesos per kilowatt hour?
6 pesos.
Is converting ac to watts and dc to watts the same watts equals volts times amps?
Converting AC to watts and DC to watts involves the same formula: watts = volts x amps. However, for AC circuits, an additional factor called power factor (cosine of the phase angle difference between voltage and current) needs to be considered to account for any phase difference between voltage and current.
Your dehumidifier is 820 watts and 3.5 amps how much electricity does it use in 24 hours and what kwh usage?
To calculate the total electricity usage in 24 hours, you multiply the wattage by the number of hours: 820 watts * 24 hours = 19680 watt-hours or 19.68 kWh. To convert that to kilowatt-hours, divide by 1000: 19.68 kWh.
What is the difference between Watts and Kilowatt hours?
Watts measure power, which is the rate at which energy is consumed. Kilowatt hours measure energy usage over time. One kilowatt hour is equal to using 1 kilowatt of power for 1 hour.
What is a difference between vollage and watt?
Watts = Volts / Ohms Watts = Volts x Amps
How many watts if 4 kW for 6 hours?
"Watt" is a rate of using energy."4 kW" means 4,000 watts."4 kW for 6 hours" means 4,000 watts for 6 hours.If you use energy at the rate of 4 kW for 6 hours, then altogether you use24 kilowatt-hours, or 24,000 watt-hours, or 86,400,000 joules.
How much can a 15W circuit breaker handle?
Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.
How much diesel fuel is consumed by a 1KVA diesel generator to produce 1000 watts?
There's really no telling. Watts is an instantaneous measurement, not a sustained value. You could make 1000 watts for a fraction of a second using only the tiniest amount of fuel. Or you could churn out 1000 wats for hours and hours, using Diesel by the gallons.
What is imperial unit of energy equal to 750 watts?
An imperial unit of energy equal to 750 watts is 0.75 kilowatt-hours (kWh). This means that using 750 watts of power for 1 hour consumes 0.75 kilowatt-hours of energy.

77000 watts for 30 days is how many kilowatt hours?
Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
Find the kilowatt hours used if 300 watts are used for 8 hours?
300 watts 0.3 kilowatts; 0.3kilowatts X 8 hours 2.4 kilowatt-hours
