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 5.60×10^11 Na+ ions enter each meter of the axon during a time of 10.0 ms . What is the current during this inflow of charge in a meter of axon?

The current during this inflow of charge in a meter of axon is

Explanation:

Given that,

Number of sodium ions

Time, t = 10 ms

Let q is the charge flowing through nerve axon. It is given by :

The electric charge per unit time is called electric current. it is given by :

So, the current during this inflow of charge in a meter of axon is

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
