Timeline for Birds on a wire (again) - how is it that birds feel no current? They are just making a parallel circuit, no?

| Mar 30, 2020 at 15:03 | comment | added | Dmitry Grigoryev | @Gnudiff If you have DC in your house then you definitely won't feel a thing. The pictures I have posted have DC voltage sources in them, not AC. DC lines do exist, and they have lower power losses compared to AC. Touching a live AC wire is possible if you wear a Faraday suit (that's how critical AC lines are repaired under voltage). | |

| Mar 29, 2020 at 15:08 | comment | added | paleonix | @Gnudiff The problem is AC. Each contact will change between voltages with high frequency. So theoretically if you would touch a contact in exactly the right moment for a very short time you wouldn't get shocked. | |
