A) \[60{}^\circ \]
B) \[45{}^\circ \]
C) \[30{}^\circ \]
D) none of these
Correct Answer: B
Solution :
Deflection in tangent galvanometer \[\tan \theta =\frac{I}{K}\] where K = reduction factor \[\tan \theta =\frac{1}{1}\] \[=1=\tan {{45}^{o}}\] \[\therefore \] \[\theta ={{45}^{o}}\]You need to login to perform this action.
