amazing facts abt electronics !!!!!! Electricity travels at the speed of light more than 186,000 miles per second! If you had a light bulb on the moon connected to a switch in your bedroom, it would take only 1.26 seconds for that bulb to light up, 238,857 miles away. If you traveled as fast as electricity, (about 300,000 kilometers = 186,411.358 miles per second the speed of light), you could go around the world 8 times in the time it takes to turn on a light switch. A spark of static electricity can measure up to three thousand (3,000) volts. A bolt of lightning can measure up to three million (3,000,000) volts and it lasts less than one second! Thomas Edison didn’t invent the first light bulb but he did invent one that stayed lit for more than a few seconds. Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters. Ben Franklin didn’t discover electricity but he did prove that lightning is a form of electrical energy.’ According to the U.S. Energy Information Administration, electricity consumption will increase by 51 percent from 2002 to 2025. The first power plant owned by Thomas Edison opened in New York City in 1882. The first central power plant ? Pearl Street Station in lower Manhattan, built by Thomas Edison began generating electricity on September 4, 1882. Pearl Street had one generator and it produced power for 800 electric light bulbs. Within 14 months, Pearl Street Station had 508 subscribers and 12,732 bulbs. Since the first power plant lit up 800 light bulbs in 1882, the electric utility industry has grown to generate over 2.5 million gigawatt-hours annually, the equivalent of lighting 4.8 billion 60-watt light bulbs for a year. If you scuffed your feet long enough without touching anything, you would build up so many electrons that your finger would explode! But this is nothing to worry about, unless you have carpeting. The electrons travel through your bloodstream and collect in your finger, where they form a spark that leaps to your friend’s filling, then travels down to his feet and back into the carpet, thus completing the circuit. Approximately 0.01 Amps of current is enough to kill.Scary, isn’t it? There aren’t very many machines that you will find that use less than .01 Amps. Electrocution is one of the top causes of workplace deathsThis is a sad, but very true, fact. Anything from a loose wire to water being in the wrong place can cause a worker to be electrocuted. Always be on the lookout for any electrical hazards, including loose wires, spills, water leaks, etc. A loud person may become quiet; a quiet person may become loud and obtrusive. Electrotherapy is still used today for this very reason; an electrical shock can change the behavioural patterns of any person. The electric eel can generate up to 500 Volts at 1 Ampere This is a disgusting fact, but I felt that I had to mention it. The electric eel doesn’t zap itself because the organs responsible for the release of electricity are located in its tail. Water conducts the electricity and pulls it away from the eel. If you give a static shock when touching a touch lamp, the lamp won’t turn on This was bizarre, but give it a try. A touch lamp turns on because of sensors that detect a change in the capacitance when a person or animal touches it. However, somehow the sensors are not set off when a static shock is applied. If you were to put a battery into a flashlight backward, and then added a lot more voltage, eventually the flashlight would turn on… just before it explodes.There is a long explanation for this, but just trust me. Don’t try it. The electric chair was invented by a dentistThe dentist’s name was Alfred P. Southwick. It was Thomas Edison’s employee who actually built the chair It is suspected that lightning actually works from the ground up.While it is widely believed that a bolt of lightning shoots from the sky, a slow-motion video was taken a number of years ago showing lightning working from the ground up. Doesn’t this scare you when you think about hooking to ground before doing some electrical work? A static shock that you can see, hear, and feel is approximately 250 Volts of electricity (but can definitely be higher than that) The next time that you’re in the dark, moving blankets around and watching sparks fly (no joke intended), think about all the electricity that you’re generating.Human beings can handle significant amounts of voltage; it’s the current that kills people Current takes the easiest path with the least resistance, going through the body and back to ground. If the path of least resistance happens to be across your chest, your heart will stop.
