Considered as non-lethal weapons, electroshock weapons stop assailants by disrupting superficial muscle functions. Operating as high voltage, low current devices, stun guns are able to stop even the most determined attacker. Even though these types of weapons are considered non-lethal, their use is in question because they are highly dangerous in untrained hands.

• Stun guns are low ampere devices. Most stun guns deliver 1 to 2 milli amperes. This is significantly lower than the 1 ampere needed to fatally injure someone.
• High voltage is needed in electroshock weapons to pass through heavy clothing and skin.
• While considered non-lethal, improper usage of these types of weapons can and have resulted in fatal injuries.
• Other variants of stun technology include stun belts, electroshock batons, and even liquid based electroshock weapons.

Using the information provided above, answer the following questions.

1. Why do stun guns need to be low current instead of high current?
2. How can a stun gun produce 1 million volts when it is only powered by a 9 V battery?
3. Why does the voltage from a stun gun need to be high in order for it to be effective?
