The action potential occurs when the voltage across a cell membrane experiences an increase from the...
The action potential occurs when the voltage across a cell membrane experiences an increase from the resting potential (−70.mV) to about 30.mV. This depolarization, in turn, causes a similar response all along the cell membrane; the result is an electrical impulse that sends a signal along the axon of a neuron. The cell membranes can be about 5.0nm across and have an electric field across them due to the change in potential. What is the electric field across the membrane...
