and
and the
following 
graphs
are obtained.
Which
of the graph is/are correctly labelled in terms of the words series and
parallel? Justify your answer.
Answer:
In
the first graph, slope of V-I graph is resistance. Since in series combination,
resistance is more than the resistance in parallel combination, therefore,
slope of V-I graph for series combination is more than the slope of V-I graph
for parallel combination. Hence, graph is correctly labelled. (1)
In
the second graph, slope of V-I graph is 1/resistance. Hence, second graph is
also correctly labelled. (1)
