Web14 jul. 2015 · As all the shells are in series, we can integrate the expression to give the total resistance. Here we go: Area of shell: A = 4 π r 2. Resistance. δ R = ρ δ r A = ρ δ r 4 π r 2. Total resistance: R = ∫ a b ρ d r 4 π r 2 = ρ 4 π ( 1 a − 1 b) Incidentally you can see that if a goes to zero, this resistance becomes infinite - just ...

Why does electrostatic potential inside a conducting spherical shell ...
WebYou have to use the moment of inertia of the spherical shells in your derivation, which is d I = 2 3 r 2 d m = 2 3 r 2 d ( 4 π r 2 d r) Integrating this will give the correct answer. Remember, you're adding up the spherical shells, not individual point masses, so this changes the calculation.
