1/1

Human body is a conductor of electricity. When any two parts of the

body are at two different potentials an electric cur rent will flow

Basics of electrical shocks

ELECTRICAL SHOCK Causes & Consequences

Wet conditions are common during low-voltageelectrocut ion. Under dry conditions, human skin

is having high resistance (approx. 1,00,000ohm). Wet skin dramatically drops the body

resistance (approx. 1000 ohm)

Dry conditions: Current = Volts/ Ohms = 120/1,00,000 = 1mA

Wet conditions: Current = Volts/ Ohms = 120/

1,000= 120mA, which is sufficient to causeventricular fibrillation

LOW VOLTAGE DOES NOT IMPLY LOW HAZARD!
