Parameters for effects of electric current

The effects of electric current depend on the following parameters:The body resistance (also called body impedance) depends again on the following factors:
  • Current path in the body, that is, how the current flows through the body and at which points the current enters and exits the body (e.g. right hand – left hand, right hand – both feet, right hand – thorax). The current path determines which tissues or organs are inflicted by the current.
  • Touch voltage, i.e. the voltage between conductive parts when touched simultaneously by a person.
  • Duration of current flow
  • Current frequency
  • Skin moisture (e.g., dry, wet, sweaty)
  • Size of contact area (e.g., fingertip, palm of the hand)
  • Exerted pressure
