I understand basically that the current, or amps, are what cause harm, but based on Ohm’s law, V=IR, for the amps to be so low with such high voltage, the resistance must be very high. So why do you need such a high voltage in the first place? Wouldn’t that require a transformer to step up the voltage? And doesn’t such a high voltage create a safety risk, for instance if a conductor with lower resistance came into contact with the voltage source? If you want low amps as not to electrocute animals/people, would it not be easier to use lower voltage?
Just curious and trying to understand. Electricity is like magic to me.

Having grown up on a farm the rule of thumb was that more volts meant fewer cows walking through fences. The understanding always was that it was the amps side of the equation that was deadly so more volts equals more better! Higher voltages also seem to allow current to jump farther so it made a prettier light show at night. In fact fences are not even the highest voltage things most people deal with. Some of the spark plug wires out there run at 30,000+ volts and if they’re not shielded will interfere with radio signals which is super annoying when you’re in the middle of harvest racing around the clock and your only source od entertainment is being jammed.
