1 Voltage doesnt matter!
2 AC 60hz, not DC. I dont know the state of safety education in US, but in Europe it was the first thing on the first day of EE lab. Quick google:
"The threshold for ventricular fibrillation for direct current shocks longer than 2 seconds is 150 mA as compared with 50 mA for 60-Hz shocks; for shocks shorter than 0.2 seconds, the threshold is the same as that for 60-HZ shocks, that is, approximately 500 mA"
so >2 seconds at 45 volts if you jam two live wires at 45V into your open wounds across the heart
and here are some funny, but educational yt clips

- DanBC 12y agoThe downvotes are because you are wrong. You start this post saying "Voltage doesn't matter!" but end it with "so >2 seconds at 45 volts if you jam two live wires at 45V into your open wounds across the heart" - so which is it? https://van.physics.illinois.edu/qa/listing.php?id=1335 https://van.physics.illinois.edu/qa/listing.php?id=1335 https://www.physics.ohio-state.edu/~p616/safety/fatal_current.html https://www.physics.ohio-state.edu/~p616/safety/fatal_curren... Fatal current is between 100 mA and 200 mA. Internal resistance of human body (and this doesn't require "open wounds") is between 300 ohms and 1k ohm.
- rasz_pl 12y agoOhms law. Voltage doesnt matter because its a redundant information, only current matters.
