Engineering question
Use a 3D DC-conduction model of the water and simplified body; at 60 Hz the displacement current is negligible, so the current through the body can be calculated from the DC field solution.

Simulation problem
Problem Type
3D problem of DC conduction.
Electrical conductivity values are taken from the book by G. S. Cargill III "Electric Shock Drowning: Causes and Prevention".
Water electrical conductivity is 0.15 S/m, body electrical conductivity is 0.12 S/m
Lamp voltage is 120 V, ladder is grounded.
Calculate the electric potential distribution in the water and current through the body.
We use a simplified human body model so the problem can be constructed by extrusion from the plane.
The lamp is operating at AC voltage. At 60 Hz frequency the displacement component of the electric current is negligible, so we run the analysis at DC voltage.
Electric current through the thorax is 14.7 mA.
