Space between tow concentric spheres of radii `r_(1) and r_(2)` such that `r_(1) lt r_(2)` is filled with a material of resistivity `rho`. Find the resistance between inner and outer surface of the material

Two concentric spheres of radii a and b have a space in between the spheres which is filled with a material of resistivity rho . Resistance of the intermediate material is

Sphere of inner radius a and outer radius b is made of p uniform resistivity find resistance between inner and outer surface

Sphere of inner radius a and outer radius b is made of p uniform resistivity find resistance between inner and outer surface

Sphere of inner radius a and outer radius b is made of p uniform resistivity find resistance between inner and outer surface

There are two concentric spheres of radius (a) and (b) respectively. If the space between them is filled with medium of resistivity rho , then the resistance of the intergap between the two spheres will be

The mutual inductance between two planar concentric rings of radii r_(1) and r_(2)(r_(1) > r_(2)) placed in air is given by:

There are two concentric spheres of radius a and b respectively. If the space between them is filled with medium of resistivity rho , then the resistance of the intergap between the two spheres will be (Assume bgta )
