Answer / raj

in order to get shock voltage should be more than 70v either
DC r AC if the voltage more than 70v then we will get shock
even the current is in mA

Answer / pillay

to feel a shock, a flow of current should occur.The flow of
current depends on the potential difference and the
resistance posed by US when touched.
try touching both terminal ends of a battery of higher
voltage rating say 75volts and above.
