A hollow spherical conductor having inner radius 'a' and outer radius 'b'. A constant potential difference is applied across inner and outer shell. Due to which current flows radially. Select the correct statement :-
Options:
Answer:
C
Solution:
From microscopic Ohm's law . For radial flow in a sphere , so .
As r increases from a to b the area increases and the drift velocity decreases - option (C).
