A metal rod of length L has a resistance of 15 Ω when the current flows in the direction of L. 4 The metal rod is cut into three equal lengths that are then stacked on top of each other to form a new rod with length L/3. What is the resistance of this new rod, when the current flows along the L/3 length?
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.
