How many horsepower per KWH?
Horsepower is a unit of energy delivery rate, while KWH is a unit of total energy. The two units are not convertible. It is true that, for an electric motor, 1 horsepower is defined as 746 watts, or 0.746 KW, but KWH is an entirely different thing.
If an appliance draws 10 amps and the line voltage is 110 volts the power consumed is?
The equation that you are looking for is Watts = Amps x Volts. Power is consumed at that rate over a time constant. You are billed by the electrical utility company by the kWh. 1000 watts are equal to 1 kW.
What is the monthly energy cost of leaving a 60W bulb on continuously if electricity cost 10 cents kWh?
The formula you are looking for is Watts/1000 x hours in the day x cost per kWh.so it is 1,500
How much electrical energy does electric fan with a power rating of 100 watts use in 1 hour?
It varies tremendously depending upon the size of the fan and the power of the motor. The best way to answer your question would probably be to look at the back of the fan, or on the bottom. It usually will tell how many watts the fan draws. If it only tell amps and volts, remember that watts = amps X volts. Remember that watts does not have a time component; so to say that it draws a certain number of watts in an hour is not correct. You should rather ask, "How many watt-hours does it consume in an hour?" That is the number of watts times the number of hours that it drew that number of watts.
How much does it cost to run a 500 watt bulb?
There are two things missing in this question. The period of time the 1000 watts is being used and the price that you are paying for a kWh. If the 1000 watts was left on for an hour it would be 1 kWh. The cost per kWh is still needed, so it can be multiplied the the 1 kWh, to find a cost.
How many watts does the standard heat pump use?
About 3 kWh's of heat are created for every kWh of electricity it consumes
How many 2196 kWh in 1000000000 w?
KWh is an amount of energy, w(watts) is a rate of energy (power). You can't equate them.
How many kilowatt hours - KWh - are used to light a 30 watt light bulb for 1 hour?
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
What is the kwh of 2 hp motor at 4500 rpm?
1hp = 746 watts, so 2hp would be 1492 watts, or almost 1.5 kw kWh does not convert to hp, as kWh has a time component.
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.
How many kwh is used by a 60 watt bulb?
A kilowatt is 1,000 watts. A 60 watt bulb uses 60 watts in an hour. So, in half an hour it uses 30 watts. Now if a kilowatt costs 20 cents, what does 0.03 kilowatt cost?
How many watts does the Android phone need?
the new galaxy s3 is insane you need 3000 kwh
How many watts does your old refrigerator use?
400 Kwh per year (1996 - 120 liters)
When you know how many watts an appliance uses how much time passes for those stated watts?
Watts are an instantaneous measurement of power. Meaning, when you measure how many watts an appliance is using, that is the power required to operate it at that exact moment in time. When people use the term kWh, it means an amount of power being consumed over a period of time. As an example, one kWh is 1000 watts over the span of an hour.
How many watts does a mini refrigerator use per day?
A mini refrigerator uses about 70 watts per hour or 0.07 KWH.Therefore it uses about 24 times 0.07 KWH, or 1.68 Kilowatt Hours per day.There are varied sizes of "mini refrigerators" and varying degrees ofinsulation, so the wattage may vary from 40 watts per hour to 100 watts per hour or .96 KWH to 2.4 KWH per day
How many watts does an average fridge use?
New energy star models are about 470 kWh per year.
Your dehumidifier is 820 watts and 3.5 amps how much electricity does it use in 24 hours and what kwh usage?
1000 watts = 1 KW, so: 820 watts = 0.82 KW 0.82 KW * 24 hours = 19.68 KWH
