Ohm's Law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance.
          According to the Ohm's Law,
                   
                            V∝I
         or,.             V=IR
                            here,V= Potential difference
                                      I= Electric Current 
                                     R= Resistance
               The S.I. unit of residence is ohm                       and it is denoted by Ω.
