Sustained current as small as 2.55E-6 A passing through the human heart can be fatal. Suppose a patient is undergoing open-heart surgery, and the patient’s heart has a constant resistance of 4.90E2 Ω. What is the minimum voltage across the heart that could pose a danger to the patient (in V)?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
