Latest Electrical phenomena Stories
There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect.
Every year, scientists learn something new about the inner workings of lightning.
A freak bolt of lightning struck a 56-year-old cyclist in Englewood, Colo, even though no electrical storms were reported in the area, authorities say.
Duke University researchers have captured images of lightning bolts shooting upwards.
A 38-year-old bricklayer in the British town of Kettering says he is lucky to have survived being struck by lightning while walking his dogs. The Daily Mail Monday said Brad Gifford was hit by a 300,000-volt bolt of lightning while attempting to seek shelter from a thunderstorm by ducking under a tree. Gifford suffered burns to 11 percent of his body and both of his eardrums were burst.
Much like humans, materials are capable of some pretty remarkable things when they're placed under pressure. In fact, under the right conditions, materials can even produce electricity.
In a Nature letter published July 23, 2009, Norwegian researchers present evidence that the auroras in the Northern and the Southern hemispheres can be totally asymmetric.
U.S. government scientists say they have created a method of measuring the intrinsic conducting properties of ferroelectric materials. The researchers at the Center for Nanophase Materials Sciences at the U.S.
Experts say 2009 already has been proved a dangerous year for lightning strikes in the United States and warn the worst may be yet to come. National Weather Service lightning expert John Jensenius said 11 people have been killed in the United States by lighning strikes just this month as the particularly dangerous summer months get under way, ABC News reported Monday. Last year was an exceptionally good year for not having fatalities.
When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...
A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...
Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...
Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
