How does a stun gun work?
Home » Gadgets » Stun Guns » How does a stun gun work?Stun guns run on battery power—usually from a 9-volt battery—and as long as you have the trigger depressed, the battery will maintain an electric charge between the prongs. You simply have to touch the prongs to the attacker. Unlike a real gun, therefore, a stun gun doesn’t “shoot” anything.
When you touch a charged stun gun to a person’s body, however, it causes the person intense pain and a loss of muscle control. The charge interrupts communication signals from the brain to the body, confusing the body and rendering the person disoriented and unbalanced. At the same time, the energy from the charge enters the muscles, causing them to work rapidly but inefficiently, and within a few seconds, the person’s blood sugar has depleted, making movement tremendously difficult. You will, however, need to hold the stun gun charge to the person for several seconds before the person is completely immobilized.
A stun gun works on all people and even works through clothing. It makes no difference where on a person’s body you place the charge, but a shock to the torso will be most effective.
The person may be immobile for up to fifteen minutes, but the charge almost never causes permanent damage because of the low amperage in the charge and the fact that the charge does not affect any vital organs. On the rare occasions when a person does suffer permanent injury, it is usually caused by a preexisting heart condition that is aggravated by the electric shock.
