As I understand it, voltage is the difference in charge between two points. The greater that difference, the greater the current because more electrons will flow between the two points.
I thought a high resistance might explain this, but apparently the metal in electric fences have very low resistance.
In: Physics
Imagine popping a pimple. You have to squeeze really hard (high voltage), but when it pops only a little bit of stuff comes out (current).
The voltage is kept high on the fence so that it can overcome enough resistance to shock you, but there’s just not a lot of current available to shock you that much.
