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.
A device rated at 1000 watts consumes 1000 joules per second.
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.
The KWH meter measured the energy (voltage and current) being used in its watt-hour tally.
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
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.
A device rated at 1000 watts consumes 1000 joules per second.
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).
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.
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.
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.
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.
The KWH meter measured the energy (voltage and current) being used in its watt-hour tally.
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.
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.
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.
