W” indicates actual power consumption, while “VA” is potential power. The electricity used by electrical appliances when they are actually working is called power consumption (W).

Running watts are the continuous watts needed to keep items running. Starting watts, are extra watts needed for two or three seconds to start motor-driven products like a refrigerator or AC unit. See similar questions...

The running watts of a generator equals the amount of power the unit can produce continuously, while the starting wattage is the additional power that the generator can produce for short rentalperiods of time to start items in your home that require larger amounts of electricity for initial start-up than when they are running.

Ans. The equation is kW= kVA *pf. In general kW is active or useful power and kVA is the vector sum of active power and reactive power. The equation is kW= kVA *pf. See similar questions...

These may not be our most "Frequently Asked Questions," but they ought to be, because power and energy are Frequently Confused Concepts. Power is the rate of energy release at a given instant in time-how much energy is released per unit time at that instant. Energy is power integrated- added up-over time. Power is measured in watts, kilowatts, and horsepower. Energy is measured in joules (watt-seconds) or kilowatt-hours. See similar questions...

A They are both measurements of heat output. To convert from Watts to BTU, simply divide by 0.293. To convert BTUs to Watts multiply by 0.293 See similar questions...

This applies to GaAs lasers. When a GaAs laser works in a pulsed fashion, the laser light power varies between the peak pulse output power and zero. Then usually the laser's average power output is of importance, especially in terms of dosage calculation. The peak pulse power value is of some relevance for the maximum penetration depth of the light. Some manufacturers specify only the peak pulse output in their technical specifications.

A former homicide detective who was convicted of shooting and killing a suspect with a banned handgun. He was frozen in 1998 and paroled by the mayor. He began to make a profit from the ban and sold on the black market. He kills Devon Miles and attempts to kill Shaun until Michael shoots him and kills him. See similar questions...

Use a calculator, conversion table (pdf) or equation to convert the power units. Here is a short conversion table: Note, doubling the wattage increases dBm by 3. Here is a more comprehensive tutorial on Using and Understanding Decibels. The maximum output power allowed for wireless Ethernet (802.11, 802.11b, etc.) by the FCC at 2.4Ghz is 36dBm or 4Watts.

First keep in mind that Watts and Calories are two different units of measurement that can't be directly converted back and forth. However if you use Watt- Hours instead of just "Watts" you then have a way to convert to calories. Here are the steps: So for this example let's assume that you provide pedal power to a 100 Watt television for one hour. See similar questions...

A typical person can easily generate power up to about 50 Watts for about 20 minutes. Results will vary with age and agility. See similar questions...

that constant current which, if maintained in two straight parallel conductors in infinite length, of negligible circular cross section, and placed 1 meter apart in a vacuum, would produce between these conductors a force equal to 2x10^-7 newton per meter of length." joules per coulomb) The electromotive force required to drive a steady current of 1 ampere through a resistance of 1 ohm See similar questions...

Generally you should check the label on your blower to figure out how many watts and amps it uses. You should always figure your renters will inevitably end up using the extra plugs for cotton candy machines, stereo's ect. See similar questions...

Most PA Public Announce speakers get around the problem of handling LOUD DEEP bass at 40 hertz, by designing PA Public Announcement speakers NOT to move at 40 Hertz, and NOT to produce 40 Hertz sound ! ) Of course, 1 piece of 6 inch domestic speakers are totally useless for LOUD DEEP 40 Hertz bass note in 20 feet room (which does not have 12 decibel bass boost / resonance at about 50 Hertz of a 10 feet by 10 feet by 10 feet room.)

Most of our heated grips use about 30 watts, PER PAIR, at 12.0 volts (the voltage of a partially discharged battery with the engine off). At typical voltages, with the engine running above an idle, the electrical system will be providing about 14 volts. At this voltage - the grips will use about 42 watts per pair. Keep in mind that wattage ratings are a poor method of judging the relative heat output between competing products. See similar questions...

Seriously, the 2.4 GHz frequency is absorbed by water (think microwave ovens) and wood, and what isn't absorbed is reflected. Think about the 5000+ leaves on a tree blowing in the wind. 5000+ little reflectors interfering with your 2.4 GHz signal. Thus 2.4 GHz signals do best in free space, or in line of sight applications. When you think line of sight you probably think about a line, right? Unfortunately it's not that simple. See similar questions...

Watts are watts. But a tube amp with a certain wattage rating will likely be capable of producing louder, pleasing music than a solid state amp of equivalent wattage. When I was a kid, I saved up my money and bought a Silvertone 2x12 100W solid state amp to replace the little portable tube PA my Dad gave me to play through. The other guys in my band were using a silverface Bassman and Bandmaster. See similar questions...

UV-C: 24-26 Watts. Bulb: 36 watts each, hot cathode. This is the spec for the Blue, DSL, and Airtronics UV air purifiers. The high output duct mounted UV air purifier features 120 watts. The Mini-Blue furnace / A/C duct mount air purifier features 2 18w lamps with short lamps for tight areas. See similar questions...

You need to check how many Watts your applience operates on (You can find this information on a label on the bottom or back of your equipement, or in the manual). If you can't find this information, you can try to find information on amperage (AMPS) of your appliance and multiply it by input voltage (110V or 220V) to arrive at the total wattage. Volts x Amps = Watts (i.e 110V x 0.5 AMPS = 55W). Please make sure not to run any applience with higher wattage then woltage transformer's wattage. See similar questions...
