_______i did parts a and b and the hw programs says i am right, but am stuck on part c.
A typical cell membrane is 8.0 nm thick and has an electrical resistivity of 1.3* 10^7 Ohm·m.
(a) If the potential difference between the inner and outer surfaces of a cell membrane is 75 mV, how much current flows through a square area of membrane 1.2 µm on a side?
______1.03*10^-12 A
(b) Suppose the thickness of the membrane is doubled, but the resistivity and potential difference remain the same. Does the current increase or decrease?
______It Decreases (and i found it to be 4.15*10^-12A
c) What factor does it decrease by?
