A cell membrane has a resistance and a capacitance and thus a characteristic time constant.

What is the time constant of a 8.5 nm -thick membrane surrounding a 3.8 x 102 mm -diameter spherical cell? Assume the resistivity of the cell membrane as 3.6 x 106 m and the dielectric constant is approximately 9.0.
