does electricity weigh anything?

Yes the electricity is electron flow,which is the  number of electrons flowing in a cross section of a conductor for one oscilation .\nElectrons have an electrical mass which is equal to \n9.1 x10^-31kg.\nso if you take the number of electron per oscilation times the mass of the electron you have the total electrical mass flowing,\nYou take the total mass(assuming acceleration relative to the earth's center of mass)times 9.8 m/sec^2 would equal the weight of the electrical mass flowing.Hence a used battery would weight less.\nFor the simple reason that in the reaction gas has formed and evaporated and the excess electrons have dissipated and lost mass in the form of heat.\nThe weight difference can only be calculated. since the mass loss is very minute.The mass lost would be energy expanded by the battery divided by C^2.

Weight can be determined by mass and the pull of gravity exerted on an object. But mass is not an indication of weight. Mass is presumed to be constant through varying gravities while weight fluctuates because it is proportional to both of these variables.

Every physical object has mass, even in space.  You might be refering to weight, which is a whole differnet story.  Outside the pull of the eath's gravity you will have no weight, but you will still have mass.  Your weight is determined by gravity/acceleration, on the moon you will weigh 1/6th what you weigh on earth.  In space you will weigh 0 but you will still have the same mass in all three situations.  Mass is the amount of stuff you, and everything else, is made of.  Weight is relative to where and how you weigh.

Scientists are now saying the Earth is a little lighter than we thought. The calculated weight is 5.978 sextillion metric tons, or 5,978 followed by 18 zeros. But the latest measurements show the true weight is actually 5.972 sextillion metric tons. So, does this mean the Earth is losing weight? \n\nActually, the answer is no. The truth is, one of the constants used to calculate the weight of the Earth was off. The force of gravity, shown as the capital letter G, is a little tricky to measure. Scientists have come up with many different numbers, and each one gives us a different number for the Earth's weight. \n\nScientists at the University of Washington found a more precise way to measure G. And now that they have this more exact measurement, they have found the real weight of the Earth - they think. They warn that their findings may still change, so don't use the new weight in your science homework just yet. \n\nWho knows, maybe the Earth is losing weight!

none. amps has no weight, its a flow of current. It's like calculating tonnage to speed. How many tons does 100 mph represent?

If you lift a 100 pound weight with only 50 pounds of force, the weight will remain on the floor because of inertial (it is pulling down more by gravity than you are pulling up).  Although you may be greatly exerting yourself, you have added no energy to the weight.  If you now lift with an upward force of 101 pounds, you overcome the downward force of the weight and it rises.  Importantly you are now adding potential energy to the weight.  Lift the weight one foot and you have added 100 foot-pounds of potential energy by doing work (force times a distance) on the weight.  We know that a pendulum can convert potential energy (height) to kinetic energy (motion) continuously until stopped by friction (that converts the energy to heat and sound, etc.).  Therefore, a body will remain at rest until you add energy to it and it will then remain in motion until the energy is removed again.  Energy is added when a force acts on the weight for a distance and energy is removed when the weight acts as a force moving a resistance a distance.  This is simple in a frictionless (ideal) system but in fact friction often applies a force to the weight removing its energy in the form of heat.  Hope that helps a little.

To nitpick (we all love to do that) very accurate weight measurements (for example in a lab) must be taken in a total vacuum or otherwise compensated for the bouyancy of air.  For example how much does a hot air balloon weigh?  It depends on whether it is cold on the ground or hot in the air; where it would have negative weight.  So a pound of feathers weighs the same as a pound of bricks if weighed in a vacuum because their densities (weight per volume) are greatly different.  But only you know if this was a trick question.  Good luck.

Here's one: Measure the density of air.\n\nTake a flask, weigh it.\nVacuum out all the air, then weight it again.

I am assuming the energy in this context as "heat energy". Then the answer is NO. It depends on the temperature.\n\nHeat flows from body of high temperature to body of low temperature.\n\nImagine a small tank (10ltr) on second floor and a big tank with 100 lt on first floor. If we connect these, water flows from top tank to below tank.\nHeight is synonymous to Temperature.\nAmount of water is synonymous to Heat energy.\n\nPS: Another similarity is electricity.\nTemperature = height of water = voltage\nheat flow = water flow = current\nheat energy = amount of water = charge\nheat resistance = pipe resistance = electrical resistance

It depends on how much you use the electricity.

Best Answer Chosen By Voters:\nLet me give you a more understanding answer to what electricity is than Ubi did.\n\nTo study electricity you must first understand something very important...    \n \nWhat do lightning, a flashlight, an alarm clock battery, and a toaster have in common?\n  \n \n Are you still thinking? Here are more items to add to the list: a computer, a car battery, a light bulb, the shock you feel when you shuffle across a carpet and then touch something. Their common link isn't something magical...\nThey are powered by a form of energy called ELECTRICITY. \nIt helps us do many things.\n  \n\n\n------------------------------------------------------------\n \nThe Atom \nTo study electricity you must first understand something very important...    \n \nEverything is made of atoms. They are a very tiny particles made up of even tinier particles. The central part of an atom, called the nucleus, contains protons and neutrons. Orbiting around the outside of the nucleus are electrons. Protons, neutrons and electrons have their own characteristics. One of these is called an electrical charge. Protons carry a "positive" charge while electrons carry a "negative" charge. Neutrons carry no charge. Electricity happens when electrons get temporarily taken away from an atom.    \n \nNow that we have more information, it's time to look at our definition of electricity. \nELECTRICITY \nis a form of energy produced by the movement of electrons.   \n  \nA Little Electrical History...  \n                            Just 200 years ago, electricity was not used to power anything in the world. \n                            Who do we have to thank for discovering how to use it? \n     \n Electricity was not invented. \nIt occurs naturally in our world. People, however, have invented ways to measure it and to control it for our use. \nBen Franklin started working with electricity in 1740's. He believed that lightning was a flow of electricity taking place in nature. He performed his famous kite experiment in 1752 which proved that electricity and lightning were the same thing.\n\nLearn more about this great man and his experiment at \nThe Franklin Institute Online.  Thomas Alva Edison is another name important in the history of electricity. In the late 1800's he developed 1,093 inventions, but his most famous is the incandescent light bulb. He wanted to bring light into homes and factories. Up until then people used candles or whale oil lamps for light. \n \n\nHow many kinds of electricity are there?\n\nLet's think about the above examples for a minute... Did you notice that they don't all have wires! Electricity doesn't exist only in things with wires. The reason is that there are two kinds of electricity: static and current. \n   \n Try to figure out what types of electricity these are\nSTATIC ELECTRICITY:The Facts/ CURRENT ELECTRICITY:The Facts \na build up of electrons\n                              the steady flow of electrons between objects or places. It comes from far away on wires.\n \nstays in one place until it jumps to an object\nneeds a conductor, a substance that allows electrons to move easily through it\n \n                                   does not need a circuit \n needs a closed circuit to flow\n \nthe kind of electricity you feel after you drag your feet across a carpet and touch someone or something\n                                  the kind of electricity that powers the appliances and heat in your home\n \nlightning is static electricity on a more spectacular scale\n the kind of electricity in a battery\n\nHope this helps, worked really hard on it.

Weight is define by your mass times the acceleration due to gravity where you are.  So you mass is the same anywhere in the universe but your weight will be effected by where you are.  Now what is weight measured in?  This is dependent on the units you use for mass and acceleration.  Using kilograms for mass and m/s^2 for acceleration you will get newtons.  Use slugs and ft/s^2 you get a pound-force.  Using a standard equivalence between pounds and kilograms you get kilogram-force.  Many people think kilograms is a measure of weight when it really is not, its kilograms-force.  There should be somewhere on most scales that will show a lbf or kgf instead of just lb or kg.  Newtons is the standard SI unit of measure though.\n\nEdit: when i say acceleration, i mean acceleration due to gravity.  Weight *is* a unit of force.\n\nhoarp001:  Weight is a unit of force, all the units you put there are units of mass, not weight.\n\nzeno : "From other experiments, we know that g, or acceleration by free fall is actually an acceleration of 9.8N at sea level"  G is acceleration due to gravity.  According to your "9.8N" your mass would be a kg*N, not newtons.  Pay attention to your units, especially since he was asking a unit question.  Standard SI would be 9.8 meters / second^2, CGS would be 980 centimeters / second^2.  If using standard engineering units, it would be 32 feet / second^2.  Bascially anything that is a length per time ^2.

Considering that weight is really mass, and mass can be converted to energy, -and darkness, by this definition is void of either mass or energy, then no darkness does not have weight.\n\nBut if in the middle of night you get out of bed, and it's dark and you hit your foot on a chair, then yes, darkness does (have) (include) weight.

yes every thing i touch schocks me  \n\nWe usually only notice static electricity in the winter when the air is very dry. During the summer, the air is more humid. The water in the air helps electrons move off you more quickly, so you can not build up as big a charge.

Weight is the force on an object caused by gravity. It is usually measured in pounds in the English system and newtons in the metric system. To find the weight (in newtons), multiply the mass in kilograms (44) by the acceleration of gravity (9.81).\n\nP.S. Newtons do measure weight since weight is a force.\n\nP.P.S. Don't listen to the guy below me. The acceleration of gravity is not 10. It is 9.81 (assuming you are on the Earth). The weight would be 44*9.81.\n\nhttp://en.wikipedia.org/wiki/Gravity#The_Earth.27s_gravity
