Diode rectifier characteristic. In the reverse direction, the diode rectifier will ultimately break down. The breakdown voltage is normally well in excess of the turn on voltage-the scales on the diagram have been altered (compressed) in the reverse direction to illustrate that reverse breakdown occurs.
Common kingsnakes are beneficial for the ecosystem. As predators, they help keep numbers of rodents, frogs and other snakes like rattlesnakes and cottonmouths in check. They are eaten by larger snakes and predatory birds and mammals. They also get some parasites from the group apicomplexans.ommon kingsnakes are eaten by alligators in Florida, larger snakes, hawks, raccoons, striped skunks, and Virginia opossums. They defend themselves from predators by hissing, striking, making a striking pose shaped like an S, biting, and flying.
The king cobra's generic name, Ophiophagus is a Greek-derived word which means snake-eater, and its diet consists primarily of other snakes, including rat snakes, small pythons, and even other venomous snakes such as various members of the true cobras (of the genus Naja), and the krait.his is akin to the human sense of smell. When the scent of a meal is detected, the snake flicks its tongue to gauge the prey's location (the twin forks of the tongue acting in stereo); it also uses its keen eyesight; king cobras are able to detect moving prey almost 100 m (330 ft) away.
