Resistance Of A Cylindrical Resistor

April 30, 2018

A cylindrical copper rod has resistance r. The cylindrical resistor in figure 1 is easy to analyze and by so doing we can gain insight into the resistance of more complicated shapes.

Imagine that the resistor is made by squirting material whose conductivity is s into a cylindrical mold with length l and cross sectional area a as shown in figure 1.

Resistance of a cylindrical resistor. The longer the cylinder the more collisions charges will make with its atoms. Of course the resistance between points is undefined since the total current through a point for any given current density will be zero. Imagine thatthe resistor is made by squirting material whose conductivity is into a cylindrical mold with length and cross sectional area.

Another wire of the same material. Your task is to calculate the resistance of a simple cylindrical resistor with wires connected to the ends such as the carbon composition resistors that are used on electronic circuit boards. Imagine that the resistor is made by squirting material whose conductivity is s into a cylindrical mold with length l and cross sectional area a as shown in.

Your task is to calculate the resistance of a simple cylindrical resistor with wires connected to the ends such as the carbon composition resistors that are used on electronic circuit boards. The cylindrical resistor in is easy to analyze and by so doing we can gain insight into the resistance of more complicated shapes. The current density is the same in two wires.

Resistance of a cylindrical resistor. It is reformed to twice its original length with no change of volume. The resistance of an object depends on its shape and the material of which it is composed.

As you might expect the cylinders electric resistance r is directly proportional to its length l similar to the resistance of a pipe to fluid flow. A hollow cylinder has length l and inner and outer radii a and b. A certain wire has resistance r.

A potential difference is set up between the inner and outer surfaces of the cylinder each of which is an equipotential surface so that current flows radially through the cylinder. Wire a has the free electron concentration of wire b. Your task is tocalculate the resistance of a simple cylindrical resistor withwires connected to the ends such as the carbon compositionresistors that are used on electronic circuit boards.

It is made of a material with resistivity r. Anyways at aaas im sure you are meant to calculate the resistance between the two diametrically opposed line segments of length d and for that just use the method i described in my second post.
