The current strength, which is dangerous for human life, is 0.05 A. The resistance of the human body between its hands changes and can drop to 800 ohms. At what minimum stress can a person die.
Initial data: I (current strength, which will be dangerous to humans) = 0.05 A; R (minimum resistance of the human body) = 800 ohms.
The minimum voltage at which a person can die can be calculated using the formula (Ohm’s law for a section of the circuit): U = I * R.
Calculation: U = 0.05 * 800 = 40 V.
Answer: A person can die at a minimum voltage of 40 V.
