If a man hangs on one live wire with to hands, will he get shocked

That’s why electricians use insulated gloves, rubber boots, etc. They add resistance, stopping electricity if accidental contact happens.

Electric shocks are no joke. Low voltages can hurt, and high-voltage lines are deadly. Shocks can cause:

Burns: Bad ones where electricity enters and exits.
Cardiac Arrest: Heart rhythm gone wrong.
Nerve Damage: Maybe paralysis or chronic pain.
Muscle Damage: Strong shocks make muscles contract hard, leading to fractures.
