Answer / selvakumar

The contact(finger touch) is connected in series with the
pulp with metallic line contact through a resistor. The
resistor drops sufficient voltage such that we wont have a
shock while testing.
Complete isolation of our body from earth is impossible
unless we float in the air.Depending on the insulation
(shoes,bare legs,wood,Rubber mat...,,) to ground the light
intensity varies.
