⌛ 110/120 volt appliances bring lower bills.

Electrical Question: How many ExPats does it take to change a light bulb in the Kitchen? Answer: None, make the Wifey/GF do the dishes in the dark! Joke joke......

 

Well, I guess I'll open this can of worms a little more. I was told by an electrical engineer for an appliance company over barbque and beer one day that the "watts rating" printed on an appliance is a very closely guarded process. There is no 100% standardization for coming up with this rating. Of course, every manufacturer wants their rating to be the lowest.
To get this "rating", the manufacturer will place the unit in a perfectly controlled temperature area (usually 78F) and place a certain amount of "product" (usually water) in the unit, run the unit until it is at normal interior temperature and all of the product is also. Then using a very closely monitored voltage supply, as listed on the plate, will run the unit for a given time (usually 24 hours) and measuare wattage used. This is the usage as stated on the data plate.
Obviously, the carefully controlled conditions are such that can almost never be duplicated in the real world of the homeowner, but it makes for great selling points (" our unit uses less energy then their unit")
as with most things, it's all in the advertisement, not the real world.
The best disclaimer known to man is on auto milage stickers ("your milage may vary")

 

Measure Watt consumtion....

To be precise about electric consumtion our appliances AMP's (amperes) can be measured by using a AMPEREMETER. When we know the Amp's, and Voltage, the WATTS is a given.

Voltage x Amp = Watt

Did you know the following......

WATTis named after the Scottish engineer James Watt (1736–1819). The unit measures the rate of energy conversion. It is defined as one joule per second.

VOLT is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, possibly the first chemical battery.

AMPERE is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics. In practice, its name is often shortened to amp.

OHM is the SI unit of electrical resistance, named after Georg Simon Ohm.


Christmas quiz: 1 KW (1000 watts) = 1.34 Horse power.
1 Horse Power = 746 watts

So the question is, how many horses do you need to run your households electric consumption.
hUUUMMMM......???????????????

For you WATT guys ....many other Watts below....

Femtowatt
The femtowatt is equal to one quadrillionth (10−15) of a watt. Technologically important powers that are measured in femtowatts are typically found in reference(s) to radio and radar receivers. For example, FM tuner performance figures for sensitivity/quieting and signal-to-noise require that the RF energy applied to the antenna input be specified in order to be meaningful. These input levels are often stated in dBf (decibels referenced to 1 femtowatt which is equal to .2739 microvolt across a 75 ohm load or .5477 microvolt across a 300 ohm load) so that the specification takes into account the RF input impedance of the tuner.


Picowatt
The picowatt is equal to one trillionth (10−12) of a watt. Technologically important powers that are measured in picowatts are typically used in reference to radio and radar receivers, and also in the science of radio astronomy.

Nanowatt
The nanowatt is equal to one billionth (10−9) of a watt. A surface area of one square meter on Earth receives one nanowatt of power from a single star of apparent magnitude +3.5. Important powers that are measured in nanowatts are also typically used in reference to radio and radar receivers.

Microwatt
The microwatt is equal to one millionth (10−6) of a watt. Important powers that are measured in microwatts are typically stated in medical instrumentation systems such as the EEG and the EKG, in a wide variety of scientific and engineering instruments and also in reference to radio and radar receivers.

Milliwatt
The milliwatt is equal to one thousandth (10−3) of a watt. A typical laser pointer outputs about five milliwatts of light power, whereas a typical hearing aid for people consumes less than one milliwatt.[2]

Kilowatt
The kilowatt is equal to one thousand (103) watts. This unit is typically used to express the output power of engines and the power consumption of electric motors, tools, machines, and heaters. It is also a common unit used to express the electromagnetic power output of broadcast radio and television transmitters.

One kilowatt of power is approximately equal to 1.34 horsepower. A small electric heater with one heating element can use 1.0 kilowatt. The average annual electrical energy consumption of a household in the United States is about 8,900 kilowatt-hours (cf the average UK household's approx 4,700 kilowatt-hours for example), equivalent to a steady power consumption of about 1 kW for an entire year.[3] Also, kilowatts of light power can be measured in the output pulses of some lasers.

Megawatt
The megawatt is equal to one million (106) watts. Many events or machines produce or sustain the conversion of energy on this scale. For example: lightning strikes, large electric motors, large warships, such as aircraft carriers, cruisers, and submarines, engineering hardware, large Server farms or data centers and some scientific research equipment, such as supercolliders, and in the output pulses of very large lasers. A large residential or commercial building may consume several megawatts in electric power and heat.

The productive capacity of electrical generators operated by a utility company is often measured in MW. On railways, modern high-powered electric locomotives typically have a peak power output of 5 or 6 MW although some produce much more—the Eurostar, for example, consumes more than 12 MW—while heavy diesel-electric locomotives typically consume 3 to 5 MW. U.S. nuclear power plants have net summer capacities between about 500 and 1300 MW.[4]

The earliest citing of the megawatt in the Oxford English Dictionary (OED) is a reference in the 1900 Webster's International Dictionary of English Language. The OED also states that megawatt appeared in a 28 November 1947 article in the journal Science (506:2).

Gigawatt
The gigawatt is equal to one billion (109) watts or 1 gigawatt = 1000 megawatts. This unit is sometimes used for large power plants or power grids. For example, by the end of 2010 power shortages in China's Shanxi province will increase to 5–6 GW.[5] and the installed capacity of wind power in Germany was 25.8 GW.[6] The largest two units (out of four) of the Belgian Nuclear Plant Doel each has a peak output of 1.01 GW.

Though obscure, the "j" sound is still an accepted pronunciation.[7][8]

Terawatt
The terawatt is equal to one trillion (1012) watts. The total power used by humans worldwide (about 16 TW in 2006) is commonly measured in this unit. The most powerful lasers from the mid-1960s to the mid-1990s produced power in terawatts, but only for nanosecond time frames. The average stroke of lightning peaks at 1 terawatt, but these strokes only last for 30 microseconds.

Petawatt
The petawatt is equal to one quadrillion (1015) watts and can be produced by the current generation of lasers for time-scales of the order of femtoseconds (10−15 s). Based on the average of 1.366 kW/m2 of total solar irradiance[9] the total energy flow of sunlight striking Earth's atmosphere is estimated at 174 PW

ConstantElectrical and thermal watts
In the electric power industry, megawatt electrical (abbreviation: MWe[10] or MWe[11]) is a term that refers to electric power, while megawatt thermal or thermal megawatt[12] (abbreviations: MWt, MWth, MWt, or MWth) refers to thermal power produced. Other SI prefixes are sometimes used, for example gigawatt electrical (GWe).[notes 1]

For example, the Embalse nuclear power plant in Argentina uses a fission reactor to generate 2109 MWt of heat, which creates steam to drive a turbine, which generates 648 MWe of electricity. The difference is due to the inefficiency of steam-turbine generators and the limitations of the theoretical Carnot Cycle.

Confusion of watts, watt-hours, and watts per hourThe terms power and energy are frequently confused. Power is the rate at which energy is generated and consumed.

For example, when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt-hours (W•h), 0.1 kilowatt-hour, or 360 kJ. This same amount of energy would light a 40-watt bulb for 2.5 hours, or a 50-watt bulb for 2 hours. A power station would be rated in multiples of watts, but its annual energy sales would be in multiples of watt-hours. A kilowatt-hour is the amount of energy equivalent to a steady power of 1 kilowatt running for 1 hour, or 3.6 MJ.

Terms such as watts per hour are often misused.[13] Watts per hour properly refers to the change of power per hour. Watts per hour (W/h) might be useful to characterize the ramp-up behavior of power plants. For example, a power plant that reaches a power output of 1 MW from 0 MW in 15 minutes has a ramp-up rate of 4 MW/h. Hydroelectric power plants have a very high ramp-up rate, which makes them particularly useful in peak load and emergency situations.

Major energy production or consumption is often expressed as terawatt-hours for a given period that is often a calendar year or financial year. One terawatt-hour is equal to a sustained power of approximately 114 megawatts for a period of one year.

 

LOL! Would you really like to eat off dishes that were cleaned in the darK, or worse yet, eat food that was prepared and cooked in the dark?

So maybe the punchline of that joke should be...

Question: How many ExPats does it take to change a light bulb in the Kitchen?

Answer: Just 1 expat... to hand his Brother-in-Law a new light bulb and point at where it needs to go..

 

Awe come on guys I'm not asking to "repeal" the law but it seems it can need amendment per circumstances of each device used and even ohms could still learn something about energy...and the interface of math principals and its interface with physics and im not talking the laws/theory of it but the actual enigma of physics... A LAW IS A MENTAL NOTE OF WHAT YOU THINK YOU OBSERVED AND TESTED REALITY TO BE REGARDLESS OF WHAT KIND OF STONE YOU ETCHED IT IN...REALITY?,,,well it is...I think...????

 

I don't believe Sir Ohm, Watt, Volta or Ampere learn anything from power-bills in Dumaguete and I am totally sure you don't create that rules new with solar-panels and voltage regulators

 

Best answer yet! :D

 

And as far as all of those explanations go, I didn't like learning them in school 40 years ago, and they mean even less to me now.
My advice......just pay the electric bill and live with it.
An old biker motto from the US applies here.....DILLIGAF
Every biker knows what that means.
Lol

 

RonEtue - almost nobody nowdays evens knows what a "horsepower" is equal to in work performed.
If I remember, without looking it up (and wasting my valuable time), it is the amount of power (energy) need to raise 220 pounds 100 feet in one minute. Transversely, raise 100 pounds 220 feet in one minute. Someone decided that was the amount of power of a normal size draft horse pulling up a weight vertically.
Of course, that is only my memory from 40 years ago, so some of you with more time and energy than me can correct me if I'm incorrect.
Cheers.....beer time for me.

 

The law of Physics never change....The rules are the same no matter what!
Noreco and Solar Power came after the 4 gentlemen, Volta, Ampers, Watts and Ohm......and of course their theories is still the law.

Save energy this Christmas...eliminate brownouts.

Cheers, Ron
