Problem 1P

Problem 1P

Two concentric metal spherical shells, of radius a and b, respectively, are separated by weakly conducting material of conductivity σ (Fig. 7.4a).

(a) If they are maintained at a potential difference V, what current flows from one to the other?

(b) What is the resistance between the shells?

(c) Notice that if b≫ a the outer radius (b) is irrelevant. How do you account for that? Exploit this observation to determine the current flowing between two metal spheres, each of radius a, immersed deep in the sea and held quite far apart (Fig. 7.4b), if the potential difference between them is V. (This arrangement can be used to measure the conductivity of sea water.)

Step-by-Step Solution:
Step 1 of 3

Potential Energy and Conservation of Energy Conservative and Nonconservative Forces ● Conservative force: The work it does is stored in the form of potential energy that can be used at another time. ○ Gravity is a conservative force ○ Friction is a nonconservative force ● Conservative forces are path independent ● Work done by a nonconservative force is path dependent ● If we pick up a block and put it on a shelf, we have done work on the block. We can get that energy back if the block falls off the shelf; in the meantime, we say the energy is stored as potential energy. ● Springs ○ Conservation of Mechanical Energy ● The initial energy of the system is the same as t
