Human body can resist up to 30mA only...

Answer / vikram veer singh

the typical values for current are given below :-

BODILY EFFECT DIRECT CURRENT (DC) 60 Hz AC 10 kHz AC
------------------------------------------------------------
Slight sensation Men = 1.0 mA 0.4 mA 7 mA
felt at hand(s) Women = 0.6 mA 0.3 mA 5 mA
------------------------------------------------------------
Threshold of Men = 5.2 mA 1.1 mA 12 mA
perception Women = 3.5 mA 0.7 mA 8 mA
------------------------------------------------------------
Painful, but Men = 62 mA 9 mA 55 mA
voluntary muscle Women = 41 mA 6 mA 37 mA
control maintained
------------------------------------------------------------
Painful, unable Men = 76 mA 16 mA 75 mA
to let go of wires Women = 51 mA 10.5 mA 50 mA
------------------------------------------------------------
Severe pain, Men = 90 mA 23 mA 94 mA
difficulty Women = 60 mA 15 mA 63 mA
breathing
------------------------------------------------------------
Possible heart Men = 500 mA 100 mA
fibrillation Women = 500 mA 100 mA
after 3 seconds
------------------------------------------------------------
since the resistance of human body is about 1 mega ohm.
so calculate the voltage by ohm's law..

Answer / k.prakashchandra

Voltage 50V under normal condition and 25 V in damp condition.

when voltage increases then current also increases then what is the need of over voltage relay and over current relay? can we measure over voltage and over current by measuring current only?
