PHYSIOLOGICAL EFFECTS OF ELECTRIC CURRENTS

Charles Maier, Chuckie Wuckie Enterprises, NE Philadelphia, PA, "Electrical Effects on the Body," Star*Tech Journal: the Technical Monthly for the Amusements Industry, August 1982

Service people who work with electricity face the hazard of electrical shock, and should make every effort to understand the danger.

The chart shown [at right] is a dependable guide for predicting the physiological effects of electric currents. Notice that it is the current that does the damage. Currents above 100 milliamperes or one-tenth of an ampere are considered fatal. However, if someone is available to turn off the power source and administer immediate treatment, a person may encounter currents exceeding 200 milliamperes and live to tell about it.

Current is forced through the resistance of a circuit by voltage. The lower the resistance the more current that can be forced through the circuit for a given amount of voltage.

Current flow through the human body depends on the resistance of the part of the body through which the current is flowing.
