We said that the Neuron is basically a concentration cell. And we can use the nurse equation to calculate what the voltage difference is between the inside and the outside of the cell due to our potassium ions. So 2.3 multiplied by R, the Gas constant 8.3, 114 multiplied by T, the temperature Inside the body. So that's 310 Degrees Kelvin, or Simply 310 Kelvin divided by Z, which is basically one in this case divided by F farades constant, which is about 96,500. Now, the concentration of potassium outside, according to our table, is five millimolar. And outside or inside, is 130 millimolar.
