Electric energy usage on your electric bill is measured in?
Electric energy usage on your electric bill is measured in kilowatt-hours (kWh). This indicates the amount of electrical energy consumed over a period of time.
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.
How much energyin kilowatt-hoursis transferred when a 2400watt washing machine is used for 60 minutes?
The energy transferred can be calculated by multiplying the power (2400 watts) by the time (1 hour = 60 minutes): Energy = Power x Time. 2400 watts * 1 hour = 2400 watt-hours. To convert watt-hours to kilowatt-hours, divide by 1000: 2400 watt-hours / 1000 = 2.4 kilowatt-hours. Therefore, 2.4 kilowatt-hours of energy is transferred when a 2400 watt washing machine is used for 60 minutes.
How do you compute electrical consumption of a device?
A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist
What unit is household electricity measured in?
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.
How many watt-hours are in 6 kilowatt-hours?
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
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.
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
How many kilowatt-hours do 50 w used for 12h equal?
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
Is watts usage measured in hours?
Power consumption is measured in kilowatt hours.
What is the difference between kilowatt hours and kilowats?
Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.
If a 100 watts bulb is on for 10 hours then what will be the amount of consumed electricity?
100 watts × 10 hours = 1000 watt hours = 1 kilowatt hour (= 1 kwh) = 1 unit of electricity.
What is 550 watt in kwh?
To convert watts to kilowatt-hours (kWh), you need to divide the wattage by 1000. In this case, 550 watts is equal to 0.55 kilowatt-hours (550 / 1000 = 0.55 kWh).
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.
Convert 250watt sound output in kilowatthour?
Think of the names. Watt. Kilowatt hour.A kilowatt is 1000 watts. Multiply 250 watts by (1 kilowatt/1000 watts) , so you have 0.25 kilowatts. Multiply this by how many hours the sound is being produced.
How many kilowatt-hours does a 50 watt fluorescent light bulb use in 24 hours?
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
Is 1000 watt equal to 1 kilowatt?
Yes, but.... KWH = KW * H So any numbers that satisfy this equation are also one KWH. For instance: * 250 watts for 4 hours * 500 watts for 2 hours * 1000 watts for 1 hour * 2000 watts for 0.5 hours * 4000 watts for 15 minutes * etc. Keep in mind that kilo- means thousands, so KW means thousands of watts ( 1KW = 1000W).
