世界上能够放电的鱼有500多种。由于种类的不同,各种会发电的鱼所发出的电流强度也不一样,有些能够发出极强的电流,能够电死一条大鱼,甚至渔人也会被击得浑身麻木。比如生活在非洲一些河流里的一种鱼——电鲶,它发出的电压高达350V。在美洲有一种叫电鳗的鱼,其电压还要高,最大电压竟可达882V。海洋里的电鳐也是发电能手,它发出的电压虽然不高(只有50-80V),但电流却很大。在太平洋北 There are more than 500 kinds of fish that can discharge in the world. Because of the different species, the currents emitted by various types of fish that generate electricity are different in intensity. Some of them can send extremely strong currents and can electrically kill a large fish. Even fishermen can be knocked out and numb. For example, a type of fish that lives in some rivers in Africa - electricity, it emits a voltage up to 350V. In the Americas, there is a kind of fish called electric cockroach. Its voltage is even higher, and the maximum voltage can reach 882V. The electric power in the ocean is also an expert in power generation. Although the voltage it emits is not high (only 50-80V), the current is very high. North Pacific
