How many volts can a human withstand?

I'm curious to know, just how many volts of electricity can a human body safely withstand without sustaining serious injury or even death? Is there a specific threshold that scientists have identified, or does it vary depending on factors like the duration of exposure, the path the current takes through the body, and the individual's overall health and resistance to electrical shock? I'm eager to gain a better understanding of this fascinating and potentially dangerous topic.
