A cylindrical conductor has resistance of R0 = 120 Ω. It has length L, radius of the cross section r, and resistivity ρ. Express the resistance in terms of L, r, ρ. R0 = I have tried r L/ρ ,( ρ L/r ),L/r, r L/ρ, ( ρ L/r ), ( P L/π r2 ), and ( ρ L/π r2 ) None of these are correct please help me figure out the correct equation.
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.
