Question

Define Ohm's law in detail?

Answer 1

V = IR
according to the ohms law, current is directly proportional to the p.d across the metallic conductor provided temperature,. area of cross section and material remain constant

Answer 2

                                         OHM'S LAW

At a constant temperature, the current that is flowing through a conductor is directly proportional to the potential difference across the ends of conductor.
-------------------------------------------------------------------------------------------------
If current I is flowing through a conductor having potential difference V then,

                  I is proportional to V
                  V = R x I    where R = resistance (a constant)

Here conclusion can be drawn that -->
i) Current is directly proportional to potential difference
ii) Current is inversely proportional to resistance.

When you plot a graph between V and I then the resistance will come same every time.
