Kunal Srivastava 8 years ago

It states that's applied potential is directly proportional to the electric current . i.e V~ I i.e V=IR For the conductor which obyes ohm law V nd I has a linear relationship and they are known as ohmic conductor .And for non ohmic conductor V,I is non linear nd they don't obey ohm law but V=IR can be applied to find the resistance at any point. ** If uh need graph then use Modern ABC or Pradeep or any other reference book you have.
