a man can experience a current frm minimum how many volts??

Answer 1

On very wet skin (i.e. your tongue) you can sense current from as little as 7.5 Volts DC, or less than 6 Volts AC (60Hz)

For normal skin it takes well over 50 Volts DC to gain sensation of the current, or about 10 Volts AC.

Ground fault interrupters are generally designed to shut down when leakage current exceeds 100 to 200 microAmps (at 120 Volts AC)
