Remarkable electric shock I experienced

Finally, something that makes sense!

It was lineman, it is going round in my head now but what a great tune.

Can't help wondering if it was a smooth sinusoidal or rectified signal that allowed Campbell to 'hear her through the wire'...

Is he still on the line?

It is nothing to do with clean or dirty AC, or harmonics or saw tooth wave forms or bouncing pulses etc. It's just the well understood electrical circuit in which current flows.

I suspect you will still keep repeating the same thing over and over again though until someone agrees with you. I suspect this won't happen.

Et tu Brutus.

Tim Horward, my apology for taking so long before responding. In my early career a Linenan shared with me his experiencing grabbing with both hands a single "live", in operation, 69kv line while standing in his bucket-Truck's extended, isolated bucket -He said that it was vibrating..., but made no remark of whether it felt warm.... Your above pgotograph shows a higher voltage transmission line -maybe 138kv.

Here's what I concluded as to why an office's single 120vac cut but live wire could set up a current through my hands, arms, and chest..., but the man with both hands on a high tension wire and sitting on a helicopter's platform does not have a delta-V nor current flow through his hands, arms and chest: High Tension wires have clean sinusoidal AC voltage produced by a Generato, transformed and transmitted through transformers; where as in offices operating all sorts of electrical devices these end-use equipment can set up harmonics and/or have partially failed or poorly designed input rectifier-transformers circuits that can "ping-back", impress, induce multiple frequency sinusoidal harmonics, or sawtooth, square wave, or othet repetitive spike, variant voltage on a single line -And this is what hung me.... You could take a bird or a man sitting below a helicopter of a line with thes delta-V's and they too would be shocked by current flowing through their hands (or bird's feet) and Body.

This concept was not realized by me until this experience; although, I knew about harmonic that computers can set up and cause undue heating on "live" wires.

I felt a similar experience in my local store yesterday.
I pressed the usual buttons, but then as the costa coffee machine started to fill the cup, I noticed that the price had gone up again.
The shock was terrible.
