Question

The capacitance of biological membranes is about 1.0 μF per cm² of membrane area, so investigators can determine the surface area of a cell membrane by using intracellular electrodes to measure the membrane's capacitive reactance. An investigator applies a 1.0 μA peak current at 40 kHz to a cell and measures the peak out-of-phase voltage--that is, the component of the voltage due to the capacitive reactance of the cell membrane--to be 0.16 V. What is the approximate capacitance of the cell membrane? A. 2.5×10⁻¹¹ F B. 1.0×10⁻¹¹ F C. 2.5×10⁻¹¹ F D. 5.0×10⁻¹¹ F
