Question

A conductor of length 5 cm and cross section area of 0.5 2 find out the resistance if the resistivity of the material is 1.22 × 10−2 Ωm.​

Answer 1

Answer:

resistance of an object depends on its shape and the material of which it is composed. 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. As you might expect, the cylinder’s electric resistance R is directly proportional to its length L, similar to the resistance of a pipe to fluid flow. The longer the cylinder, the more collisions charges will make with its atoms. The
