To send 10% of the main current through a moving coil galvanometer of resistance 99 O the shunt required is______________?
Correct answer: A. 11 O
- A. 11 O
- B. 9 O
- C. 100 O
- D. 9 O
Explanation
The galvanometer carries 10% of the total current, while the shunt carries 90%, or nine times the galvanometer current. Thus R_s = 99/9 = 11 ohms, so option a is correct.
