What did Benjamin Franklin do ? He played a kite in the rain for what ? was he srike by lightning ?

There's debate that that actually happened.  The prevailing theory of the time was though, no joke, that in order to study electricty, you first had to experience it first hand.\n\nOther things he did:\nhttp://en.wikipedia.org/wiki/Benjamin_Franklin

If you're talking about the Benjamin that played with electricity a lot, I believe he has no middle name. Benjamin Wade is someone different.

Didn't he build the ark before the rains came?\n\nHere is a suggestion:\n\nOnce upon a time they say, they say\nNoah built a big ark\nFor family, friends, and animal pairs.\n\nAnd the rains came down day after day\nAnd he sailed away in the dark\nTil the day he saw land everywhere.

Benjamin Franklin realized that electrical charges came in two types, which he called positive and negative. \n\nRubbing smooth wool over rough wax produces a huge static electric charge on both the wax and the wool, and the charge can be released in the form of a spark. It was clear that electricity was flowing from one to the other, but which way? Franklin couldn't tell, so he guessed, assigning a "positive" electric charge to the wax and the "negative" electric charge to the wool. \n\nIt turned out he was wrong, but it took over a century to discover that.

There is a great article to read on this, from How Stuff Works.  Its under "How Lightning Works", but it talks about both lightning and thunder.  My students got a lot out of it.

The exact reason is not proven, but suspected that it is because precipitation falls to the ground carrying electrons, and the lightning occurs when the difference in charges between the clouds and the ground even out, and the electrons jump back to the clouds.  That is why lightning is said to go from ground to the clouds.

Edison was an inventor or maybe an engineer but NOT a scientist. \n\nHe lived in New Jersey. He built one of the first modern research labs, with specialists from many different fields. With his team, he pioneered movies, and improved the telephone. He invented the grammophone. He lead the development of the lightbulbs we use today. \n\nThere is a huge amount of information about him on the web. Look him up.

Nobody invented electricity - it is a naturally occuring phenomenon (for example - lightning) that has been around as long as Earth. Benjamin Franklin is often credited with discovering the properties of electricity (although this is probably a myth), and Thomas Edison invented the electric light.

Answer:\nThe birds sit touching only one line and nothing else through which electricity can flow to the ground. This means no current flows through the bird’s body.\n\nSo can I get electrocuted if I touch a power line?\n\nAnswer:\nYES!!! And here is an example to explain why.\n\nYou are out flying your kite and it gets away from you. The kite ends up in the power lines. No harm comes to the kite, much like the bird. But once you get involved in trying to recover the kite danger occurs. If you use a pole of some sort to knock the kite down, the pole becomes a conductor of electricity. When the pole touches the kite, the current flows through the kite into your body and then to the ground. Your body cannot handle such a massive shock and can result in death.

Ben Franklin, electricity.  (You asked for discovery, not invention)

Ben Franklin was a shrewd politican.  That almost certainly means he lied on a regular basis.

first why do we need his moving 30 meters and what does it mean anyway? i don't understand the question here.. first he let the kite and it was flying and the string made an angle of 47 degrees.. and then he walked somewhere 30 m? so now it is an angle of 39 degrees? i could say some little things to help only:\n\n-we watch a man as a spot that doesn't move\n-a string has first brace at force T1, and it is equal the strength of wind that is flowing against kites dimension S.. so it is T1=S(paralel) * P(paralel).. \n-this task is too complicated, i'll write it down, see your mail tomorrow and send you, it is 2 am here..\n-good night

History of Wiring\nFor centuries electricity has been a challenge to scientists. They have long known that it exists, and have discovered how to generate it on a large scale, but find it difficult to explain exactly what electricity is.\n\nWhere did it all begin?\n\nAround 600 BC Greeks found that by rubbing an 'electron' (a hard Fossilised resin that today is known as Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years, until, around AD 1600, Dr William Gilbert investigated the reactions of amber and magnets and first recorded the word 'Electric' in a report on the theory of magnetism.\n\nGilbert's experiments led to a number of investigations by many pioneers in the development of electricity technology over the next 350 years.\n\n\n\n \n\nBenjamin Franklin(in his own words)\n\n\n Franklin was an American writer, publisher, scientist and diplomat, who helped to draw up the famous Declaration of Independence and the US Constitution. In 1752 Franklin proved that lightning and the spark from amber were one and the same thing. The story of this famous milestone is a familiar one, in which Franklin fastened an iron spike to a silken kite, which he flew during a thunderstorm, while holding the end of the kite string by an iron key. When lightening flashed, a tiny spark jumped from the key to his wrist. The experiment proved Franklin's theory, but was extremely dangerous - He could easily have been killed.\n\n\n\n \n\nGalvani and Volta\n\n\n In 1786, Luigi Galvani, an Italian professor of medicine, found that when the leg of a dead frog was touched by a metal knife, the leg twitched violently. Galvani thought that the muscles of the frog must contain electricity. By 1792 another Italian scientist, Alessandro Volta, disagreed: he realised that the main factors in Galvani's discovery were the two different metals - the steel knife and the tin plate - apon which the frog was lying. Volta showed that when moisture comes between two different metals, electricity is created. This led him to invent the first electric battery, the voltaic pile, which he made from thin sheets of copper and zinc separated by moist pasteboard.\n\nIn this way, a new kind of electricity was discovered, electricity that flowed steadily like a current of water instead of discharging itself in a single spark or shock. Volta showed that electricity could be made to travel from one place to another by wire, thereby making an important contribution to the science of electricity. The unit of electrical potential, the Volt, is named after Volta.\n\n\n\n \n\nMichael Faraday\n\n\n The credit for generating electric current on a practical scale goes to the famous English scientist, Michael Faraday. Faraday was greatly interested in the invention of the electromagnet, but his brilliant mind took earlier experiments still further. If electricity could produce magnetism, why couldn't magnetism produce electricity.\n\nIn 1831, Faraday found the solution. Electricity could be produced through magnetism by motion. He discovered that when a magnet was moved inside a coil of copper wire, a tiny electric current flows through the wire. Of course, by today's standards, Faraday's electric dynamo or electric generator was crude, and provided only a small electric current be he discovered the first method of generating electricity by means of motion in a magnetic field.\n\n\n\n \n\nThomas Edison and Joseph Swan\n\n Nearly 40 years went by before a really practical DC (Direct Current) generator was built by Thomas Edison in America. Edison's many inventions included the phonograph and an improved printing telegraph. In 1878 Joseph Swan, a British scientist, invented the incandescent filament lamp and within twelve months Edison made a similar discovery in America.\n\nSwan and Edison later set up a joint company to produce the first practical filament lamp.

Lightning is an electric current. Within a thundercloud, many small bits of ice bump into each other as they swirl around in the air. All those collisions create an electrical charge, just like the one that builds up in you when you cross a carpet.\n\nAfter a while, the whole cloud fills up with electrical charges (usually with a negative charge closest to the earth). Since opposites attract each other, that causes a positive charge to build up on the ground beneath the cloud. The ground's electrical charge concentrates around anything that sticks up, such as mountains, lone trees, people, or even blades of grass. The charge streaming up from these points eventually connects with a charge reaching down from the clouds, and--zap!--lightning strikes.\n\nThe intense heat of the lightning bolt causes the surrounding air to explode outward with a gigantic boom--thunder.
