Yes. The energy consumption in both cases is 3.6 megajoules or 1 kilowatt-hour.
That's what registers on the meter outside, and that's what you pay for.
If a device is rated at 1000 watts and is used for 1 hour, it will consume 1 kilowatt-hour (kWh) of energy. To calculate the energy consumed for a different duration of use, you can use the formula Energy (kWh) = Power (kW) x Time (hours).
The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
To calculate the cost of operating a 1000-watt heater for 24 hours, first convert the wattage to kilowatts by dividing by 1000 (1000 watts = 1 kilowatt). So, the heater consumes 1 kWh per hour. Multiply this by 24 hours to get 24 kWh. With electricity costing 10 cents per kWh, the total cost for operating the heater for 24 hours would be $2.40 (24 kWh x $0.10/kWh).
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.
1400 watts.
If a device is rated at 1000 watts and is used for 1 hour, it will consume 1 kilowatt-hour (kWh) of energy. To calculate the energy consumed for a different duration of use, you can use the formula Energy (kWh) = Power (kW) x Time (hours).
Let's try this: An adult human consumes from 100 to 1000 watts. You multiply that by time to get watt-hours (or kwh).
A watt is a unit of power. 1 watt = 1 joule/second; that is, if somebody consumes 1 watt, it consumes 1 joule of energy every second. Or if there is a transfer of 1 watt, 1 joule of energy is transferred every second. 1000 watts (1 kW), of course, is simply 1000 times as much (1000 joule/second).
To calculate the kilowatt-hours of energy consumed by the appliance, first convert the power rating to kilowatts by dividing by 1000 (5.00 x 10^2 W = 0.500 kW). Then calculate the energy used in kilowatt-hours by multiplying the power in kilowatts by the time in hours (15.0 minutes = 0.25 hours). Therefore, the appliance consumes 0.500 kW x 0.25 hours = 0.125 kWh of energy.
I'm not entirely sure I understand the question. Watts are a measure of power. Power (watts) applied over time consumes energy. Voltage x Amperage = watts 1000 watts is one kilowatt. One kilowatt applied for one hour consumes 1 kilowatt hour of energy.
Power = (voltage) x (current) = 110 x 5 = 550 wattsIf operated at this level for 1 hour, thenEnergy = (550 watts) x (1 hour) = 550 watt-hours = 0.55 kilowatt-hour.Another AnswerAs microwave ovens don't operate continuously, but in short bursts, it's not really possible to determine an answer to your question without knowing the frequency and duration of these bursts of energy.
The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
You are confusing energy and current. You consume, and pay for, energy -not current.For the purpose of billing its customers, an electricity utility measures energy in units called kilowatt hours. In the UK, a kilowatt hour is also called a 'unit', short for 'Board of Trade unit'. The Board of Trade, which no longer exists, used to be the government organisation responsible for setting energy prices.A unit, or kilowatt hour, of energy is the amount of energy consumed at the rate of one kilowatt over a period of one hour. So, to determine the number of units that an electrical load 'consumes', you simply multiply its power in kilowatts by the time for which it operates, in hours.
We are talking about two different quantities, here. The watt is used to measure power, which is the rate at which your device is consuming energy. The kilowatt hour is used to measure how much energy has been consumed (or the work done) over a specified period of time. So you cannot simply convert one to the other. However, if you know the rate of consumption of energy, in watts, then you can determine how much energy, in kilowatt hours, your device consumes if you specify for how long that device is operating.For example, in one hour, your 60-W device will consume (60/1000) x 1 kilowatt hour. In 'n' hours, it will consume (60/1000) x n kilowatt hours. In other words, first convert the power in watts into power in kilowatts, then multiply that by the number of hours the device is operating.
To calculate the cost of operating a 1000-watt heater for 24 hours, first convert the wattage to kilowatts by dividing by 1000 (1000 watts = 1 kilowatt). So, the heater consumes 1 kWh per hour. Multiply this by 24 hours to get 24 kWh. With electricity costing 10 cents per kWh, the total cost for operating the heater for 24 hours would be $2.40 (24 kWh x $0.10/kWh).
The Nike+ sensor does not require charging. It operates on a watch battery and typically lasts for around 1000 hours of use.
