The quantity of electric charge that may be stored upon a body per unit electric potential. The membrane capacitance results from the fact that the plasma membrane acts as a capacitor: the phospholipid bilayer is a thin insulator separating two electrolytic media, the extracellular space and the cytoplasm. The membrane capacitance is proportional to the cell surface area and, together with the membrane resistance, determines the membrane time constant which dictates how fast the cell membrane potential responds to the flow of ion channel currents
