Two Spoons I need your help!
I 'm a snail farmer and i have an energiser for the electric fence which i want to decrease it's voltage. The voltage that provides with no load is 8000v and on 500ohm load 2700v. I want to decrease it for not harming the snails, but just to prevent them from escaping at about 3000-5000v volts. The model that I use is Hercules Hc 850. Input 12v 95mA, stored power 1.25Joules, output power 0.85 joules. What type of resistor do i have to use for that? I have orderd a " Rotary Wirewound Adjustable Resistor Rheostat 500 Ohm 50W". Will it do the job?Its specifications are below.
Thanks anyway my friend!

I would have thought that creatures made from mucus could be deterred by just a few volts. Exactly how big are these giant mutant snails?
