When this quantity is divided by cross-sectional area and multiplied by the magnetic permeability, it is equal to the Laplacian of the magnetic vector
When this quantity is divided by cross-sectional area and multiplied by the magnetic permeability, it is equal to the Laplacian of the magnetic vector potential. This quantity is proportional to the product of drift velocity, area, and carrier density, and it is multiplied by the differential length in the BiotÂ–Savart law. The line integral of a magnetic field around a loop is proportional to the amount of this quantity (*) enclosed according to Ampere's Law. Kirchoff's junction rule states that the amount of it leaving a junction is equal to the amount entering, and it is multiplied by resistance in Ohm's law. For 10 points, name this quantity equal to the rate of flow of electric charge that is symbolized I and measured in amperes.
