Answer / bharani

When you isolate yourself from the ground by standing on an
insulator and touch a live wire, depending on the
resistivity of the inulator, a small current may flow
through your body to the ground and if it is negligible, you
may not feel anything. but if you wet your body and carryout
the the same experiment, then you may be at risk of a shock
as yor body resistance would have come down drastically.All
said and done, the resistivity of the material chosen as
inulator is very important.

Answer / sourav pal

It depends,
1.Condition of body(non Linear Resistence) either wet condition or Dry condition.
2.Voltage Capacity(high/low)
3.On which insulator(capacitance) are u standing and touching the wire
