The long thin cylindrical axon of a nerve carries nerve impulses. The axon can be as long as 1 m. A) Estimate the capacitance of a 1.0-m-long axon of radius 3.9 ×10−6 m with a membrane thickness of 7.6 ×10−9 m. The dielectric constant of the membrane material is about 6.0. B)Determine the magnitude of the charge on the inside (negative) and outside (positive) of the membrane wall if there is a 0.065-V potential difference across the wall. C)Determine the energy stored in this axon capacitor when charged.

    please answer question 8-13 This is the prior information: Nerve impulses are electrical currents in the form of “ionic flows.” Therefore the electrical properties of the axon are important to understand in order to understand the flow of electrical impulses. In this test, you will explore the capacitance and resistivity of an axon of a nerve cell. For this test, the axon will be treated as a CYLINDER of arbitrary length “L” and radius “a” that is filled with a...
