The resistance R to the flow of blood varies directly with a blood vessels length L and inversely with the 4th power of its radius r. If R = 144 when L = 24 and r = .5 find an equation relating R, l, and r. Find R if L = 6 and r = .25.
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.
