The ability of a material to decrease or Currents of only 10A can be sufficient to cause fibrillation in this case with a probability of 0.2%. The only thing that's needed is to have some conductor or very high dielectric constant material to perturb the field coming from the screen. St Joseph Cathedral Sioux Falls Bulletin, The skin contact resistance will usually be between 1000 and 100,000 , depending on contact area, moisture, condition of the skin, and other factors. This correlates to an impedance of about 13 megohms at 60 Hz, which corresponds to a minimum of 9 uA at 120 VAC to ground. The degree of hazard present at a particular location can be determined by a detailed analysis of the electrical system, and appropriate protection worn if the electrical work must be performed with the electricity on.
