A Taser is the more commonly known form of a stun gun, a device that used to deliver a high voltage shock that temporarily immobilizes another human being. Typically, a stun gun is used by law enforcement personnel, but ordinary citizens also use stun guns as a means of self defense. Stun guns are simple electrical devices that are cheap to produce and serve as an effective non-lethal weapon.
A stun gun is composed of several simple electrical parts. The most important part of a stun gun is the power source. Typically, a standard nine-volt battery is used as the power source and generally lasts for many uses. A stun gun produces a high voltage shock at a very low current. In order to produce such a high voltage, a transformer is used to increase the battery voltage to several hundred thousand volts. Of course, energy is never created or destroyed. Therefore, although the voltage has been increased, the power output from the nine-volt battery is not changed. This means that the......
