Which of the following electric field pattern is correct inside the conductor having three materials of resistivity?
Options:
Answer:
A
Solution:
In steady conduction through the series combination, the current density J is the same in all three materials.
Since , the field is uniform within each material and strongest where the resistivity is largest - only pattern (A) shows this.
