Electric heater A has a power rating of 1kw. Electric heater B has a power rating of 800W. which transfers the most energy in 2 hours?
Electric rating of 1Kw
Is there a difference between KW and kW?
AnswerKiloWatt hours. Its a measure of energy use. It is the amount of power used over time.Energy is the ability to do work, while power is the rate at which work is done.Your water heater may have a power rating of 5 kW. If it runs for 8 hours in a day, you would use 40 kWh of energy doing the work of heating the water.
How many watts does a small ceramic heater use?
A ceramic heater uses the same amount as a regular heater. Most heater use 1500 watts so in one hour a 1500 watt home heater will use 12.5 amp hours.
How can you convert kwh to kg?
The amount of electrical energy is measured in kilowatt hours. Kg unit of mass and weight. These two are not comparable.
How many BTU does kW electric heater put out running at three phase 465 volts?
Not enough information. You didn't specify the amount of kW - and you really can't calculate that, just from the volts. Once you know the amount of kW (which is a unit of power), you still need to multiply by time to get energy. Then you can do the appropriate conversion to BTU, which is also an energy unit.

Electric rating of 1Kw
How many btu's does it take to produce the same amount heat from a 1000 watt heater?
BTU is a measure of energy, while a kilowatt is a measure of power. Energy is power times time. Energy: measured in BTU or kilowatt-hours Power: measured in BTU/hour or kilowatts. 100,000 BTU equals about 29 kWh so a 1 kW heater produces about 3400 BTU per hour.

What thermal energy is supplied by the heater in 10swhen the power is 1440w?
Since power is defined as energy/time, if you solve for energy, you get:energy = power x timeIf the time is in seconds and the power in watts, the energy is in joules.

What is electrity in units?
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
What is the name of energy amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
What is the relationship between energy power and time?
Power is the rate of moving energy. Power = (amount of energy moved) divided by (time to move that much energy)
Can a power change electric energy into heat energy?
Electrical energy is changed into heat energy ... intentionally ... every time you use a blow drier, toaster, electric oven, baseboard heater, electric clothes iron, curling iron, electric hot water heater, soldering iron, or coffee machine. Electrical energy is changed into some amount of heat energy ... unintentionally ... and is lost, whenever you use anything else electric.
How could we use kilowat hours?
A kilowatt hour (kWh) is a measure of how much energy you're using.It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour.Energy(in kilowatt-hours) = power in kilowatts × time in hours.
What is the practice of decreasing the amount of energy?
the practice of energy is when we unplug our power sources to save energy.
How can you convert kwh to kg?
The amount of electrical energy is measured in kilowatt hours. Kg unit of mass and weight. These two are not comparable.
