This equation superseded an incorrect one known as Barlow's law, which falsely implied that long-distance telegraphy was impossible, while its magnetic equivalent is called Hopkinson's law.
This equation superseded an incorrect one known as Barlow's law, which falsely implied that long-distance telegraphy was impossible, while its magnetic equivalent is called Hopkinson's law. This law's continuum form relates the electric field to the current density vector. (*) Nonlinear components such as LEDs and other semiconductors do not obey this law, while the quantity defined by this law is inversely proportional to cross-sectional area, proportional to length, and adds in series. This law states that the voltage is equal to the current times resistance. For 10 points, identify this law that shares its name with the SI unit of resistance.
