This quantity's density, symbolized by a capital J, is proportional to the electric field over resistivity.
This quantity's density, symbolized by a capital J, is proportional to the electric field over resistivity. Magnetic field strength is proportional to this quantity by Ampere's law. The amount of this quantity that enters a junction must equal the amount that leaves according to one of Kirchhoff's circuit laws. Voltage is equal to the product of resistance and this quantity according to Ohm's law. This quantity is often represented by a capital I, and it is measured in amperes. For 10 points, name this flow of electric charge that exists in alternating and direct types.
