What is an electrical injury?
An electrical injury is damage sustained to the skin or internal organs on direct contact with an electric current.
What factors determine the severity of an electrical injury?
The severity of an electrical injury depends on the density of the current, tissue resistance, and duration of contact.
What are the effects of very small currents on the body?
Very small currents may be imperceptible or only produce a light tingling sensation.
How can a shock caused by low and otherwise harmless current still cause injury?
A shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling.
What are the potential consequences of a strong electric shock?
A strong electric shock can cause painful muscle spasms severe enough to dislocate joints or even break bones, and larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest.
