Effects of Electric Current
Enjoy Playing Effects of Electric Current
Electric current flows through wires under our floors. It keeps lamps glowing and heats water for showers. It enters the skin. It makes nerves spark and muscles tighten. A light shock feels like a quick flutter. A stronger hit locks joints and can stop breathing.
The impact changes with current size. It also shifts with how long it touches tissue. The path through the body matters too. One milliamp brings a subtle tingle. At ten milliamp muscles seize and breathing may pause. A hundred milliamp running through the chest scrambles the heart’s beat and causes collapse. Nearby fields nudge nerves and trigger discomfort. Some research ties long contact with magnetic fields to cancer or memory disorders but experts still study those links.
Clinicians tap into small currents for scans and tests. Electroconvulsive therapy sends brief jolts to revive brain signals and ease severe depression. Sensors on skin pick up muscle twitches and nerve pulses for medical checks. Cutting power at the breaker and moving tools away from live parts reduces risk. Respecting those flows in labs and homes keeps everyone safe.
