Problem 19.03: Transmission of nerve impulses. Enhanced-with Solution < 10116 Constants Part A Nerve cells transmit electric signals through their long tubular axons. These signals propagate due to a sudden rush of Na ions, each with charge +e, into the axon. Measurements have revealed that typically about 5.8x1011 Na ions enter each meter of the axon during a time of 11 ms What is the current during this inflow of charge in a meter of axon? Express your answer using...
