Capacitance using an axon.. :)?
An axon membrane is 8.0×10-9 m thick.
a) Find the dielectric constant of the membrane, if the capacitance C is 100 nF for an area A = 10.0 square mm.
b) If the resting potential across the membrane is ΔV = - 90 mV, what is the charge ±Q on each surface A?
c) For this area of membrane at -90 mV, what is the stored electric energy?
C=k(eoA)/D
Basically plugging in the values however i do not know what eo is and the value of it.
Thank you for your help.
