SECTION –A
1. Calculate the number of electrons transferred between two points kept at a potential difference of 40 V
if 80 J of work is done. (2)
2. I. In a given ammeter, a student sees that the needle indicates 17 divisions in the ammeter while
experimenting to verify Ohm’s law. If the ammeter has 10 divisions between 0 and 0.5 A, then what is
the value corresponding to 17 divisions? (1)
II. In the circuit diagram given below, the two resistance wires A and B are of the same area of cross-
section and the same material, but A is longer than B. Which Ammeter A1 or A2 will indicate higher
reading for the current? Give a reason. (2)
3. I. The V-I graph for a series combination and a parallel combination of two resistors is shown in the
figure given below. Out of A and B, which one represents the parallel combination? Give a reason
for your answer. (2)
