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.
These snakes are hunters and will quietly follow their prey until they are ready to attack. They can move very fast and can speed along with their heads raised. Cobras are cannibals, which means that they will eat other snakes as well as birds, bird eggs and small mammals. Kraits feed almost totally on other snakes.
