How does a 220v outlet charge a 9000v electric fence energizer?

..if it can even do that?

I’m setting up a temporary fence for a couple of horses and I’m so confused, I find energizers with 12volts and ones with 20.000 volts. I’ve borrowed one with 9500 volts, and 1,5 joule, that I’m hoping won’t fry my thread (0,35 ohm, one copper thread and 4 stainless steel ones).

There are two main features of electricity that are often referenced: Voltage and amperage. An analogy for those terms is to imagine water flowing through a pipe, where voltage is the pressure of the water and amperage is the volume of the water.

With electricity you can transform between the two, sacrificing amperage to increase the voltage. The device that does this is called a “transformer” and there is one in the energizer for your fence wire. Very high voltage with low amperage can let the electricity give creatures a shock without dangerously frying them.
