Nerve signals in the body occur when a small voltage, called an action potential, is applied across the membrane of a cell. When this action potential is applied across a region of the cell membrane called an ion channel, current in the form of moving potassium ions will be established across the cell. If, during an action potential, a single ion channel with a resistance of 1.8 GΩ, is opened for 0.6 ms, approximately 90000 singly-ionized potassium ions travel through the channel during this time. What was the voltage of the action potential? You can approximate the ion channel to be Ohmic.
