[QUOTE="shaz, post: 734326, member: 13738"] Ultimately, it all comes down to voltage. Voltage/Resistance = Current. It's the current that causes the cow to run away. The cow forms it's own circuit when it touches the wire. When you see the term "Low impedence" - that doesn't imply anything other than the charger's ability to source current at a given voltage. All else being equal, it's the high voltage you care about. That drives everything. Think of it as pressure. NOTE: You can have extremely low output impedence but only 100volts. That will blow an audio speaker but the cow won't even notice it. [/QUOTE]
