(Taser) by

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
