Expand; Ohm's Law
Ohm's law means that in the same circuit, the current passing through a conductor is directly proportional to the voltage at both ends of the conductor and inversely proportional to the resistance of the conductor. This law was put forward by georg simon ohm, a German physicist, in his paper Determination of the Law of Metal Conductivity published in April 1826. With the development of circuit research, people gradually realize the importance of ohm's law, and ohm's reputation is greatly improved. In order to commemorate ohm's contribution to electromagnetism, the unit of resistance is named ohm in physics, which is represented by the symbol ω.
