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.
It is hard to believe but snakes have many enemies. Large birds, wild boars, mongooses, raccoons, foxes, coyotes and even other snakes are a few of the dangers snakes fall prey to. Many people find it surprising that the largest and the scariest snakes can be afraid of anything, but it is true. While they are young they are easy prey to many birds and mammals but when they are older and larger they have humans to fear. Humans hunt snakes for various reasons. Many different breeds of snakes are captured and shipped to other countries to be sold in pet shops.
