what’s it for
• a non-lethal way for police officers to
subdue criminals
• self protection
pluses
• no long term effects
• less risky
hiding the taser
• camara
• cell phone
• umbrellas
• flashlights
hows it work
• dumps electrical energy into the victim
• momentary paralysis
• muscle spasms
• PAIN
shocking
• high volts
• low amps
• “doesn’t kill”
• 20,000-150,000 volts
electrodes
• electrodes are attached to wires
• electrodes are also attached to barbs
negatives
• one shot
• reload
• new gas tank
the gas tank
• the gas tank is what sends the
electrodes towards the victim
• 15-20 feet
• pulling the trigger breaks open the gas
chamber building pressure on the
electrodes launching them out
charge?
• the stun gun usually takes a 9 volt
battery
• this powers the circuit and has many
transformers
transformers
• boost the voltage
• lower the amps
• oscillator creates a pulse or pattern
current / capacitor
• the electric current charges the capacitor
• the capacitor delivers the charge to the
electrodes
• the electrodes deliver the shock
2 electrodes
• most stun guns have two pairs of
electrodes
• outer “charge electrodes”
• inner “test electrodes”
outer pair
• Current can’t travel between the outer
pair unless something comes between
them
inner pair
• if the charge cant go between the outer
pair it goes to the inner pair
• the inner pair is close enough that it can
produce a crackling noise and spark
• the inner pair is used more as a warning
