Two conductors are made of the same material and have the same length. Conductor 1 is a solid wire of diameter 2.0 m. Conductor 2 is a hollow tube of outside diameter 3.0 m and inside diameter 2.0 m. The ratio of their resistance, R1/R2, is: CHOICES: 1. 5/4. 3/2. 3. 8. Which of the following wires has the least resistance? (Assume that they have the same resistivity.) Choices: Thin, long, and hot. Thin, short, and hot. Thin, short, and cool. Thick, long, and hot.
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.
Two conductors are made of the same material and have the same length. Conductor 1 is a
solid wire of diameter 2.0 m. Conductor 2 is a hollow tube of outside diameter 3.0 m and
inside diameter 2.0 m. The ratio of their resistance, R1/R2, is:
