When lightning strikes a metal tower or strikes near a building containing electrical equipment, a large, rapidly changing magnetic field is generated. This magnetic field induces current onto power lines, often disrupting electrical service, and also induces current into other electrical conductors such as electrical equipment and even ...
Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
Faraday cages are also used to protect people and equipment against electric currents such as lightning strikes and electrostatic discharges, because the cage conducts electrical current around the outside of the enclosed space and none passes through the interior.
Here’s how to stay safe when lightning strikes When thunder rumbles, lightning isn’t far behind. About 25 million times a year, lightning strikes the United States, according to the National ...
We walked into the house about 8:30 at night. It was almost dark – not completely – which perhaps was why we didn't notice that the lights weren't operating at full strength. The floor ...
The danger of a lightning strike depends on several factors, including where a person is when being struck, the kind of object someone is holding or even the amount of water on the person's skin.
A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...
