उत्तर १
For the same change in I, change in V is less for the straight line A than for the straight line B (i.e. the straight line A is less steeper than B). The straight line A represents small resistance, while the straight line B represents more resistance. The equivalent resistance is less in a parallel combination than in a series combination. So, line A represents a parallel combination.
उत्तर २
‘A’ shows parallel combination because in case of parallel combination, the resistance is less for their potential is less, currents is more.
