My brother in America I have felt electricity and I can say exactly what it's like.

If you still don't believe though I will gladly share the secret of how to feel it for yourself. You need only bring a fork.

Just live somewhere that 220 is the standard.

For a preview that's way way too low touch a dodgy HDMI cable, a finger will suffice if you want to feel electricity and with your tongue if you ran out of 9v bats.

That's not a dodgy HDMI cable. One of the devices, if multiple are connected together, is causing the mains electricity to be capacitively transferred across the transformer core in the power supply.

That's a dodgy power supply design because of either a cheap core design, poorly rated decoupling caps across the HV to LV side of the core or lack of earth pin.

I assume it is dodgy because it is a 5 meter cable and it was the only HDMI cable to do this, and it was purchased from a bazaar.

9V battery and tongue, or electric fence
