..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).
In: Engineering
For AC, voltages are very easily stepped up and down using a transformer.
What fries wires is the amount of current flowing. The resistance of the wire causes energy loss through heat using the formula I^2 * R where R is the resistance of the wire. If too much current flows through the wire this heat generates too high a temperature in the wire which causes it to melt (or burn)
For any domestic appliance, the voltages alone won’t cause failure as long as the current flow is managed. Of course if you tried to generate some ridiculous voltage – you can theoretically ionize air molecules that can spark across small airgaps (which is what we call lightning when mother nature does this)
