Question

Draw the graph showing the variation of potential difference as a function of current and explain how the resistance of the conductor can be obtained using this graph ?

Answer 1

Answer:

State ohm's law. How is it represented graphically? ... Ohms law states that the current flowing through the cross section of a wire(I) is directly proportional to the voltage across it(V) provided the temperature does not change and it is equal to a constant which is called resistance.
