Consider the following for problems 1 through 5: The concept of electric potential difference plays an important role in the human nervous system. A nervous impulse, for example, is an action potential that results from the temporal rising and lowering of the cell membrane potential, which in turn is caused by the equally temporal influx of sodium (Na+) ions into the cell. The sodium ions enter the cell through Hodgkin-Huxley channels, named after English physiologist/biophysicists Alan Hodgkin and Andrew Huxley....

+V 0V Detector The picture above shows part of a mass spectrometer that can be used to measure molecular charge-to-mass ratios. A charged molecule (orange circle) is ionized and accelerated through an electric potential difference into a region with a uniform magnetic field. Here the magnetic field points out of the screen. The field makes the positively charged molecules undergo circular motion as shown. By adjusting the voltage difference between the plates, one can change the radius of curvature of...

Rolling down the electric hill Distributions of electric charges in a cell play a role in moving ions into and out of a cell. In this situation, the motion of the ion is affected by two forces: the electric force due to the non uniform charge distribution in the cell membrane, and the resistive force (viscosity) due to colliding with the fluid molecules. In order to begin our analysis of this, let's consider a toy model in which the ion...
