Consider the nerve fiber discussed in Example 19.10. Assume the fiber is coated with a layer of myelin that is 100 nm thick. If the dielectric constant of myelin is the same as for a lipid layer, what is the time constant of this fiber? Ignore the gaps in the myelin sheath in Figure 19.41. These gaps are called nodes of Ranvier.
