Question: A cell membrane has a resistance and a capacitance and thus a characteristic time constant. Assume the resistivity of the cell membrane as 3.6×106 m and the dielectric constant is approximately 9.0.
Part A: What is the time constant of a 8.7nm -thick membrane surrounding a 4.2 × 102 mm-diameter spherical cell?
Please show me how work it out above question, thanks.
