How does the potential difference affect the separation of molecules in electrophoresis?

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. Current is measured in amperes (A). A current of 4 amperes means that 4 coulombs of charge pass a point in the circuit every second. Potential difference can be written as v = w Q . Here, w is work done ... Apr 23, 2008 ... (15 points) An electron is accelerated in the x (horizontal) direction from rest in a television picture tube by a potential difference of 5500 ... What is the difference between gamma rays and X-rays? What are some common sources of X-rays? What are some uses of X-rays? How can I minimise my exposure to X ... Electric potential is a location-dependent quantity that expresses the amount of potential energy per unit of charge at a specified location. Thus, if an electron with charge q = e = 1.6×10–19 C is accelerated by a potential difference ... atomic, nuclear and particle physics, (1 keV = 103eV ... A potential difference of one volt exists between two points when one Joule of work is required to move one Coulomb of charge from one point to the other. The electric potential difference between two points in an electric circuit is the work done in moving a unit positive charge from one point to the other. Potential difference is the difference in electric potential energy per unit charge between two points in an electric field.
