Suppose a biological membrane with a specific capacitance of 1 μF/cm^2 has a resting surface charge density of 0.1 μC/cm^2. Also suppose there are 50 sodium channels per μm^2 and thatwhen each opens for 1 ms, 1000 Na+ ions flow through the channel, resulting in a reduction of the potential difference (the membrane voltage). Compare this membrane’s resting potentialvoltage to the membrane voltage 1 ms after 10% of these channels open, assuming no other changes occur during this time.
