The values of body impedance depend on a number of factors and, in particular, on current path, on touch voltage, duration of current flow, frequency, degree of moisture of the skin, surface area of contact, pressure exerted and temperature.

The different parts of the humanbody such as the skin, blood, muscles, other tissues and joints present to the electric current a certain impedance composed of resistive and capacitive components.

The degree of danger for the victim is a function of the magnitude of the current, the parts of 6079-1 body through which the current passes, and the duration of current flow.

Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections.


The relationship between current and voltage is not linear because the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.
