To study the dependence of current (I) on the potential difference (V) across a resistor, two students used the two sets ups shown in figs (A) and (B) respectively. They kept the contact J in four different positions, marked (a), (b), (c), (d) in the two figures.

For the two students, their Ammeter and Voltmeter readings will be minimum when the contact J is in the position :

Options

A. (a) in both the set ups
B. (d) in both the set ups
C. (d) in set up (A) and (a) in set up (B)
D. (a) in set up (A) and (d) in set up (B)

Answer
