Resistance of our body is given as
[tex]R = 30,000 ohm[/tex]
voltage applied across the body is
[tex]V = 120 V[/tex]
now by ohm's law current pass through our body is given by
[tex]i = \frac{V}{R}[/tex]
[tex]i = \frac{120}{30,000}[\tex]
[tex]i = 4 * 10^{-3} A[/tex]
So current from our body will be 4 * 10^-3 A
