### Explanation of question 4

A moving coil instrument has a full scale deflection (f.s.d.) of100A. The instrument sensitivity is

1. 100,000/V
2. 10,000/V
3. 1,000/V
4. 100/V

The answer is :- 2

Sensitivity , where f.s.d. is the current in amperes.

Since ; sensitivity will be expressed in ohm/volts.
