Hemolysis, which consists of a change in red blood cells, decreases the value of the average electrical resistivity of the blood. Due to the rupture of red blood cells, electrically charged substances are generated in the bloodstream, causing harm to the patient. Knowing that a healthy person has an average blood electrical resistivity of 1.6 Ω.m, consider the following data from a patient's clinical procedure: • L = 2.0×10^(−3) m; • S = 2.0×10^(−6) m²; • U = 0.1 V; • i = 1.0×10^(−4) A. Determine, in Ω.m, the electrical resistivity of this patient's blood. Also indicate whether he suffered hemolysis, justifying your answer. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of UERJ Resolution 2024: 👉   • UERJ 2024 - Em um experimento, dois relógi...   Professor Thales Quirino Medeiros ================== #ENEM #physics #medicine #studies #education
