Today while repairing some electronics and wearing anti-static wristband like on picture below I got thinking - in theory, would it be possible to avoid shock while working on mains by grounding yourself using such antistatic wristband / some copper wire wrapped around your wrist?
In theory I think such band / wire should give less resistance than body to ground and it should make electrical current go through it to ground rather than through whole body to feet, but maybe I'm wrong? Also I know that anti-static wristband probably wouldn't be suitable for higher voltages / currents but it's used as proof of concept, below I also sketched what I'm talking about to clarify
yellow = mains voltage e.g. 230v AC
brown = ground
green = grounding wire running from wrist to ground
black = test specimen
We assume that in both cases on the left and right test specimen is touching ground with his both feet even though on picture it doesn't look like it and that wire is making perfect contact with his wrist and ground, and "prevent shock" means that electrical shock effects would be slightly reduced and current flowing through whole body would be much smaller
