Ohm's Law (English)

In 1825-26, Professor George Simon Om of the German Physicist and Technical University had enacted this rule.

             
                                   According to Ohm's Law, if the physical conditions are kept in the heat, then the potential difference between the ends of a resistor is proportional to the current flowing through it.

That is,

        V α I
or

    

or

     

            One unit of R is Ohm.

With the resistance R, when the source of V probability is found, the current flows in it, I flows. These three ratios follow the rule of Ohm, that is, V = IR

I-V diagram of the omy and non-omeatic device: The simpler line of red than these is the symbol of the omegle device and the black curve is denoting the Vi-i feature of the non-omegle device.

                         Actually, 'Ohm's law' is not a rule, but it defines 'resistance' of such things, which are now called 'omi resistance'. In other words, it underlines the properties of those objects whose V-I feature is a simple line. It is known that many techniques used in electrical engineering and electronics do not follow Ohm's law. Such tips are called anomalous tips.

                                              For example, diode is an anomalous device.

Characteristics of four devices (two resistors, one diode, and one battery) You can see that curve of both resistors obey the rule of ohm because these curves pass through the original point and are rectilinear. It is also clear that the other two tips do not follow Ohm's rule.
