A typical cell membrane is 8.0nm thick and has an electrical resistivity of 1.3x10^7Ω*m A. If the potential difference between the inner and outer surfaces of a cell membrane is 75mV, how much current flows through a square area of membrane 1.0μm on a side? Express answer using two significant figures. B. Suppose the thickness of the membrane is doubled, but the resistivity and potential difference remain the same. Does the current increase or decrease?
