How is resting potential different from a action potential?

the opening of voltage-gated potassium channels and the closing of sodium activation gates.

A nerve is crushed between the two recording electrodes.

1/2500 sec is the absolute refractory period.

Once the action potential has passed there are alot of K ions outside the cell and a alot of Na ions inside the cells. This would not allow another AP potential to pass as there is no concentration...

Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information...
