1. The problem statement, all variables and given/known data The giant axon of a squid is 0.5 mm in diameter, 10 cmlong, and not myelinated. Unmyelinated cell membranes behave as capacitors with 1 microF capacitance per square centimeter of membrane area. When the axon is charged to the -70 mV resting potential, what is the energy stored in this capacitance? 2. Relevant equations R = (density* length)/Area 3. The attempt at a solution I know how to get R and C is given. and V is also given. but how do i solve for E?
