(a)
State the law which gives the relation between the electric current flowing through a given conductor and the potential difference applied across it.
(b)
Draw V-I graph for a given conductor as per the law stated in above question (a).
Marking-scheme solution
(i) The potential difference, V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current, I flowing through it, provided its temperature remains the same
(ii)
