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 many watts is 20 rms watts?
Rms is watts that's the amount of watts a speaker is rated for.
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.
Is it true that volt amps are the same as watts?
No, volt-amps (VA) and watts (W) are not the same. Watts measure real power in an electrical circuit, while volt-amps represent the apparent power, which includes both real power and reactive power.
Are amps and watts the same?
No, amps and watts are not the same. Amps refer to the unit of electric current, while watts refer to the unit of electric power. Watts are calculated by multiplying the voltage by the current in a circuit.
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.
What is KVA to Watts?
Formulas you need for single phase calculations. KVA = I x E/1000, KW = I x E x pf (where pf = power factor). For your question multiply the KVA by the power factor to get KW and then move the decimal point three places to the right to get watts. They are virtually the same. A watt is volts times amps. KVA is thousand of volts time amps. KVA and KW ratings are the same.
What is 500w in Australia?
In Australia, 500 watts is the same as anywhere else in the world. It is a unit of power measurement and would represent the same amount of power whether you are in Australia or elsewhere.
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.
What is a homophone for the word hoarse?
A homophone for the word "hoarse" is "horse." Both words sound the same but have different meanings.
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.

What is 1kw of electricity?
1 kilowatt (kW) is a unit of power that represents the rate at which energy is consumed or produced. It is equivalent to 1,000 watts. Typically, 1 kW of electricity can power multiple small appliances or devices simultaneously.
