Ohm's law simply states that in the same circuit, the current passing through a conductor is proportional to the voltage at both ends of the conductor and inversely proportional to the resistance of the conductor. The law was proposed by the German physicist George Simon ohm in his paper "the measurement of the electric conductivity of metals" published in April 1826.
With the development of the research on the circuit, people gradually realized the importance of ohm's law, and ohm's own reputation was greatly improved. To commemorate the ohm's contribution to the electromagnetism, physics will be named the ohm resistance of unit, in symbolic Ω said.
