Curve Let-go-current for 50% the persons tested, i. Important parameters regarding the risk electric shock,
besides the current and time aspects, are:
- frequency the current,
- resistance the human body (depending the frequency). 99,5% could not let go. 0,5% could not let go.1.

The hazard electric current primarily depends the value the current passing through
the human body and its duration.e.e. Based
