In an experiment to measure the membrane potential of a living plant cell micro-electrodes are placed inside and outside the cell. The membrane potential is measured to be 120 mV and a current of 1.5 nA flows through the membrane .Assume that the current density in the cell is uniform. The total area of the cell membrane is 2.0 m m^(2) and its thickness is 12 mum . (a) What is the current density in the membrane? (b) What is the resistivity of the membrane ?
