闪电

一种静电放电现象

AI overview

Lightning is a powerful electrical discharge that occurs between clouds and the ground during thunderstorms. It matters because it poses a significant hazard to people, structures, and the environment when it strikes.

闪电，一般是專指對流層大氣放電，是靜電放電现象的一種。當空气作為一種介質時，空气中的各种微粒互相碰撞和摩擦便會使該空气介質兩面的正負电荷的量持續积累，這時加於該空气介質的电压也會同時增加，當局部电压达到当时条件下空气的擊穿電壓時，該空气介質的局部便會發生电击穿而持續成為等離子體，使電流能夠通過原來絕緣的空气。這時通過空气的電流也會將空氣急劇加熱，使空气膨脹而產生雷聲。闪电的电流很大，其峰值一般能达到几万安培，但是其持续的时间很短，一般只有几十微秒。由於持续时间短，闪电輸送的能量相對不大，不过闪电的功率卻可以很大。在夏季的潮湿的天气下，豐富的水份子會令該空气介質所要求的擊穿電壓降低，因此较易發生闪电，而冬季下雪时也是同一情況。概括而言，當某介质的擊穿電壓因該介质的性質改变而下降，便有較大機會发生放電現象。
