A galvanometer can be converted into an ammeter by connecting: MCQ with Answer and Explanation

A galvanometer can be converted into an ammeter by connecting:
A. A high resistance in series
B. A high resistance in parallel
C. A low resistance in series
D. A low resistance in parallel
Answer: Option D
Solution (By JKSSB Mock Tests)
An ammeter must have very low resistance so it does not alter the circuit current it is measuring. To convert a sensitive galvanometer into an ammeter, a very low resistance called a 'shunt' is connected in parallel to it. This diverts most of the current away from the delicate galvanometer coil while still allowing a proportional measurement.

Question #1
A 2 kg object is raised to a height of 5 m. The work done against gravity (g=10) is
A. 100 J
B. 10 J
C. 0 J
D. 50 J

Correct Answer: Option A


Explanation:
Work = mgh = 2 × 10 × 5 = 100 J. Force = mg = 20 N, distance 5 m, work = 20 × 5 = 100 J. This becomes potential energy stored.

Question #2
Work done by a force is zero when the angle between force and displacement is
A. 90°
B. 180°
C. 0°
D. 45°

Correct Answer: Option A


Explanation:
W = Fd cosθ, cos90° = 0, so work zero. e.g., coolie carrying load horizontally.

The temperature of a body is 122°F. In Celsius it is
A. 50°C
B. 30°C
C. 122°C
D. 90°C

Correct Answer: Option A


Explanation:
C = (122-32)×5/9 = 90×5/9 = 50°C.
