The conditions needed to produce lightning have been known for some time. However, exactly how lightning forms has never been verified so there is room for debate. Leading theories focus around separation of electric charge and generation of an electric field within a thunderstorm. Recent studies also indicate that ice, hail, and semi-frozen water drops ...

Your fillings are either gold / palladium inlays or silver-mercury amalgam. The composite or enamel fillings don't apply here. Welding fillings together will require that you have fillings in opposing teeth. It is certainly possible to weld metals together with a brief electrical current - it's done by robots in car factories every day. However, it requires ...

Because air in some way like a monument wall for electricity , imagine if you have an air bubble in closed volume in solid wall and the tension of pressure in this bubble is increasing then when the tension will be big enough the pressure is crack the wall, so crack is appear and to understand deeper we need to understand that this wall have structure like ...

Lightning branches so that it can reduce the resistance of the path it takes to the ground. As you know, when you attach two identical resistors in parallel, the equivalent resistance is lesser than that of the two in series. Branching essentially does that. It creates more and more parallel paths by which the electrons can flow, thereby reducing the total ...

Looking up "what happens when lightning strikes a house" on google (it is a .php file so I had to use printscreen) See also this youtube video. So yes, avoid taking a bath during a close by storm. Have a look at this answer What will happen when lightning strikes on the surface of the deep sea? which has some numbers of the energy in a strike. By the ...

The lightning only 'sees'positive and negative charges. If the storm clouds are negatively charged then they drag a positive charge along the surface of the ocean. When the charge reaches a certain capacitance a lighting strike will neutralize the potential. Like some people, the strike follows the path of least resistance; which is usually the highest ...

I have seen lightning hit the middle of a sea lake. ( very happy I had not gone swimming). The water did not boil enough to be observed at my distance, about 500 meters. No dead fish were washed out. A boat or a head in the sea water will become a focus for the upward streamers that will join the downwards leaders and form a path for the energy of the ...
