Question: The deflection in a moving coil galvanometer is [MP PMT 1993]
Options:
A) Directly proportional to the torsional constant
B) Directly proportional to the number of turns in the coil
C) Inversely proportional to the area of the coil
D) Inversely proportional to the current flowing
Show Answer
Answer:
Correct Answer: B
Solution:
$ \theta =\frac{NiAB}{C}\Rightarrow \theta \propto N $ (Number of turns)
