Electric shock occurs upon contact of a (human) body part with any source of electricity that causes a sufficient current through the skin muscles or hair. Typically the expression is used to describe an injurious exposure to electricity. Very small currents can be imperceptible. Larger current passing through the body may make it impossible for a shock victim to let go of an energized object. Still larger currents can cause fibrillation of the heart and damage to tissues.
