Chapter 26, Problem 93E

(a)

To determine

The potential difference between the points c and d.

(b)

To determine

If $R_1=R_2$ the segments needed to decrease the potential difference $V_n$ to less than $1.0\text{\%}$ of $V_0$.

(c)

To determine

The value of resistance $R_T$ and the value of $\beta$.

(d)

To determine

The fraction of decrease in potential difference between inside and outside of the axon over a distance of $2.0\text{mm}$.

(e)

To determine

The fraction of decrease in potential difference between inside and outside of the axon over a distance from one node of Ranvier to the next.
