Ah yes well then I'm certain you will agree then on lower voltages up to 12.5 kv its not the amps or the volts that kill its the lack of resistance and minimum separation to energized conductor. I have no degree just 30 years of working around it. In the mid to early 80s I pulled more burning overhanging limbs than I like to remember. I experienced several indirect contacts in those learning years but I learned to stay out of the path of least resistance which saved my Hyde on a few occasions. These indirect contacts were mostly barely enough to be felt and usually caused by the wind but one instance was a bit scary. On the 500 kv and above I worked later in my career no limb or body part could get within 15 feet after being qualified to work on it. It was interesting stuff to say the least. Most trims on it were set a rope and fall the whole tree.
Exactly

Exactly my point. I suggested 12 Volts DC..
But on second thought this conversation should not have happened.
My electric fence has High voltage but it doesn't kill just knock the heck out of a horse. High volts low amps. Electrical engineering is actually full of variables that fail a lot of students.
Best thing is never ever experiment with Electricity.
My two brothers (who are well educated in Electronics) and I hold long conversations about theories.
Let me present a question.
Say you have a 100 foot long extension cord. Your air compressor starts , builds up 100 psi and the pressure switch stops the electric motor as you expected. You use air and hear your compressor attempting to start but it won't. Bleed some more air off and she starts, builds up cuts off and won't restart. We, well most of us realize the extension cord is to long and under load (restart) we have a voltage drop. We get our 50 foot 3/12 extension cord out and realize we now need 10 more feet of cord but we don't have any more #12 wire and add a section of #14 instead. The air compressor works properly.
Now there are several questions. # 1, will the short section of #14 wire heat up with use?
#2, Will both the #12 and the #14 wire heat up with use ?
#3, Which end should we add the lighter wire to. At the supply or on the end between the #12 wire and the load?
Many smart men would say , well current is equal in a closed loop, (a circuit most times) so it doesn't matter.
That's the basic correct answer, but, my OPINION differs.
Here is why. My house is wired with #12 wire. Therefore it makes sense to me when #12 extension cord is plugged into the house supply I'm simply extending the house wiring THEN adding my lighter extension cord. First, I'd simply not do that but hypothetically it's a good question.
However, there are times when my brothers agree then choose to say they need more time to consider.
I'm not happy with most house wiring. Basic house wiring provides 20 amp breakers. There are exceptions where a 30 amp breaker is permitted. But lets go with the common set up.
What doesn't make sense to me is MOST light switches and wall plugs are rated for 15 amps and even though you can buy a #10 extension cord seldom are the end plugs rated for 30 amps. There is a cure but it's not something I want to get into. In my case I rewound the secondary portion of a transformer and made a step up transformer. I'm getting 125 Volts AC RMS at the compressor. Just enough to compensate for my losses. Now, I guess it's better to get back to Chainsaws. Loving my new Echo 490. Exact weight ( my bathroom scales as the old 026 Sthil and cuts as well. Weight with bar , chain, and oil. The Sthil has 18 inch bar, Echo 20. Good day.
