Can 80 watts power a 12 volt for 16 hours day?
You are confusing the units.If 80 watts can power a device for a second, the same 80 watts can power the same device for a year - assuming the generator, or whatever produces the power, continues working. A watt is a unit of power (energy / time), not a unit of energy. Thus, since you are using units of power, the 16 hours are completely irrelevant to the problem.Nor can you directly compare watts and volts. The relationship is: power = voltage x current. In SI units: watts = volts x amperes. If a device uses less than or equal to 80 watts, your 80 watts will be enough; otherwise they won't. If the specifications of an electrical device only specify volts and amperes, multiply them to get the watts required.
What is 6 to the 200th power?
It has the same value as: 6200
What is the value of zero raised to power two?
It remains the same as zero
What is the value of 10 to the second power?
10 to the second power (102) is the same as 10 x 10, which equals 100.
How does the decibel scale work?
The decibel scale is a "logarithmic" scale, meaning that in order to move up by the same amount from any starting point, you don't add the same amount, you multiply by the same amount.For example, if I increase the loudness of my harmonica from 1 watt to 2 watts, while you crank your electric guitar up from 1,000 watts to 2,000 watts, both of us doubled our original sound power, and increased our sound by the same number of decibels.It's important to understand that the number of decibels always means the size of the change from the original amount. Some number of decibels is not a quantity that you can hold in your hand. It's always a comparison between the original and the final. When you see a number of decibels stated, the original value is always lurking somewhere nearby, or else it's clearly understood.Increasing the original power means adding dB. Decreasing the original power means subtracting dB (or adding negative dB).Multiplying the original power by 10 is an increase of 10 dB. Dividing the original power by 10 is a decrease of 10 dB.Technically, the way to calculate the dB of change isdB = 10 times the log of [(new power) divided by (old power)].Some quick and easy approximate numbers to remember, so you don't have to calculate it every time:Multiply or divide by 2 ==> plus or minus 3 dBMultiply or divide by 4 ==> plus or minus 6 dBMultiply or divide by 5 ==> plus or minus 7 dBMultiply or divide by 8 ==> plus or minus 9 dBMultiply or divide by 10 ==> plus or minus 10 dB (definition)Example:-- Increase power from 1 watt to 40 watts ==> Multiply power by 40.x 40 = product of (10 x 2 x 2) = +10dB + 3db + 3db = +16 dB.This is exactly the same as the change from 1 billion watts to 40 billion watts ... still +16dB, because it's the changethat counts in dB.-- Decrease power from 100 watts to 25 watts. Divide 100 by 2 (get 50), then divide 50 by 2 (get 25).Divide by 2 the first time ==> minus 3 dB. Divide by 2 the second time ==> minus 3 more dB.So 25 watts is 6 dB below 100 watts.When referring to the standard decibel scale as a measurement of the intensity of sound, it is important to note that 0 dB is set at 10-12W*m^(-2). In the above equation for dB, if you are using the standard scale, always use 10-12 as your (old power) value.
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
How many watts of led equals 40 watts of fluorescent?
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
How do you calculate the correct cooling capacity in tonnage for a large data center?
Roughly 1 Ton of cooling is needed to cool every 3,530 Watts of energy consumed by ALL heat-producing data center equipment (server + auxiliary/power distribution equipment + cooling). The thermal power generation of server equipment in Watts is equal to power consumption in Watts. This same value can be used to express required cooling capacity in Watts. Multiplying power consumption in Watts by 0.000283 provides Tons.
1660 megawatts how many watts?
mega- means time 10^6, in other words, millionso 1660 Megawatts is the same as 1660 million watts is the same as 1.66 billion watts is the same as 1.66*10^9 watts.

How does human power output compare to the power output of a 60-Watt light bulb?
About the same for moderate work. Labourers can manage 100 watts continuously, while a horse-power is 746 watts.
Are amps and watts the same?
They can be in the same box. Amps are measured in series and volts in parallel.
What is 1kw of electricity?
1 kw means 1 kilowatt which is 1000 watts. If you use 100w light bulbs, 1kw would be the same as using 10 of those at the same time. The watt or the kilowatt is a measure of electrical power, that is the rate of producing or using energy.
Is there any way that I can set up my xbox 360 in the car?
get X-zibit to pimp your ride EDIT: Yes, you need to buy a power inverter capable of supplying power to both your XBOX and your TV. The XBOX 360 draws around 200 watts, and many LCD TV's these days draw around 30-40 watts. Both these numbers are RMS, while inverters are typcially sold labeled as Peak, which is double RMS for the same value. So search for an inverter with a peak power of 500 watts or an RMS of 250 watts, or more.
How may watts in one ampere?
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
What are the losses in resistors?
The power lost in a resistor is(the current through the resistor) times (the resistance) watts. That's the same thing as(the voltage across the resistor)/(the resistance)watts.
Is 50 Hz the same as 50W?
no, Hertz (Hz) is a measure of frequency, Watts (W) is a measure of power.
