太陽風暴的影響好像都是大範圍的,例如整個加拿大停電等等
因為大範圍的電荷累積,可以破壞輸電系統
跟人類製造的EMP又不太一樣,這個強度是可以破壞小型的電子儀器
而手電筒,別忘了,它還有鋁合金外殼,會有電 ...

大地震,誰可以頂到呢

沒人要通街照,但家中的照明也須要,加上真的發生了,也不會浪費電池亂照了。
當然最好不要發生吧,因為電力系統沒有了,電池也充了,只有用單次電了

Cree, the makers of LEDs used in many flashlights, says that one of their lines of LEDs is protected to 2kV ESD.
Incandescent light bulbs are also vulnerable to surges. Based on lamp life formula, which has a very high exponent (a couple sources put it at 12 or 13.1), destruction of a 3V lamp during a 3000V surge is virtually instantaneous (far less than a nano-second).
Cree, the makers of LEDs used in many flashlights, says that one of their lines of LEDs is protected to 2kV ESD. Under a 50kV/meter EMP, this voltage can be induced on a wire or conductor 1.6 inches long.
