Is a 1000 watt load that operates for one hour consumes the same about of energy as A100 watt load that operates for 10 hours?

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.

How much energy is consumed if device is rated at 1000 watts?
A device rated at 1000 watts consumes 1000 joules per second.
How much does it cost to run a 1000 watt light bulb in 24 hours?
a 1000 watt bulb used for 24 hours consumes 24,000 watt-hours of energy, or 24 kilowatt-hours or kWh. That is also described as 24 Units, each costing around £0.15. So the toal cost would be about £3.60.
What is kilowatt hour meter?
The KWH meter measured the energy (voltage and current) being used in its watt-hour tally.
Why each tropic level didn't receive full amount of available energy?
Once an organism consumes a living thing, it gets energy from it. In a food pyramid, only 10% of the energy is passed on to the consumer. For example if an organism had 1000 calories of energy in it, and it was eaten, the predator would have gotten 10% of 1000 or 100 calories. If an animal eats that animal, it gets 10% of 100 in energy; 10 calories. And so on... NOTE- This is why food pyramids have so few tropic levels
A battery charger uses 15 watts At 6 cents per kilowatt-hour how much does it cost to charge batteries for 24 hours?
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.
What consumes more energy 1000 watts or 1400 watts?
1400 watts.
How much energy is consumed if device is rated at 1000 watts?
A device rated at 1000 watts consumes 1000 joules per second.
Why is the daily energy requirement for humans expressed as a range rather that as a single value?
Let's try this: An adult human consumes from 100 to 1000 watts. You multiply that by time to get watt-hours (or kwh).
How many units consume for 1000 watts?
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).
How much does it cost to run a 1000 watt light bulb in 24 hours?
a 1000 watt bulb used for 24 hours consumes 24,000 watt-hours of energy, or 24 kilowatt-hours or kWh. That is also described as 24 Units, each costing around £0.15. So the toal cost would be about £3.60.
What is the calculation of kilowatts hour?
The calculation of kilowatt-hours (kWh) is done by multiplying the power consumption in kilowatts (kW) by the time in hours (h) that the power is being used. kWh = kW × h. For example, if a device has a power rating of 1 kW and is used for 2 hours, the energy consumption would be 2 kWh.
What is the total kilowatt hours used if a microwave oven operates on 5 amperes of current on a 110-volts circuit for one hour?
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.
How do you calculate current consumption per hour?
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.
What is kilowatt hour meter?
The KWH meter measured the energy (voltage and current) being used in its watt-hour tally.
What is 60watts to kwh?
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.
How much energy in kilowatt hour is consumed in operating 50w bulb for 10 hours per day in a month?
KWH is standard unit used to measure electrical energy. simply put, 1kwh is the amount of energy used by a 1KW appliance when it works continuously for 1hour. if the appliance is only 100watts, i.e, 0.1Kw, it takes 10hours for it to expend 1kwh of energy. in other words, it uses0.1KWH of energy per hour. Rest of it simple math. meaning, for a continuous activity of a 100w bulb for 24hrs, it uses 2.4 KWH of energy.
