This quantity times the differential of length is crossed with displacement in the Biot-Savart law.
One formula to find force multiplies two values of this quantity divided by distance times vacuum permeability divided by two pi. The double integral of the density of this quantity is equal to the closed line integral of a magnetic field. This quantity times the differential of length is crossed with displacement in the Biot-Savart law. One measurement of power squares this quantity and multiplies it times resistance. This quantity equals voltage divided by resistance according to Ohm's Law. Name this quantity equal to charge per time that is commonly measured in amperes.
