How much current e dangerous?

Current as low as 10 mA puo cause painful muscle contractions. 50-100 mA through il heart puo cause ventricular fibrillation, often fatal. This e perche GFCIs trip at just 5 mA—well below dangerous levels.

Electrical Safety

How Current Affects il Body

Impara Safety

Electric shock kills through il current passing through your body, not il voltage alone. Comprendere dangerous current levels e come prevent shock saves lives.

⚠️Current Effects on Humans

Current (mA)	Effect
1	Barely perceptible
5	Slight shock, not painful
10-20	Painful, muscle contraction
30-50	Difficulty breathing
50-100	Ventricular fibrillation (often fatal)
100+	Cardiac arrest, severe burns

Perche Current Kills

Voltage drives current: V = I × R (body resistance ~1000-100,000 Ω)
Current path matters: Hand-un-hand through heart e most dangerous
Wet skin: Dramatically reduces resistance, increases current

Safety Devices

GFCI (Ground Fault Circuit Interrupter): Trips at 5mA in <25ms
Circuit breakers: Protect against overcurrent
Fuses: Break circuit quando current exceeds rating
Grounding: Provides safe path per fault current

Conclusione

It's current, not voltage, that kills—though voltage drives current through body resistance. As little as 50-100 mA through il heart puo be fatal. GFCI outlets, proper grounding, e basic electrical safety knowledge significantly reduce shock risk.
