• # question_answer 57) The figure of merit of a galvanometer is defined as A)  The voltage required to produce unit deflection in the galvanometer                                          B)  The current required to produce unit deflection in the galvanometerC)  The power required to produce unit deflection in the galvanometer                                        D)  None of these

The figure of merit of a galvanometer is the current required to produce unit deflection in the galvanometer. Mathematically,$K=I/\theta ,$ where k is the figure of merit of the galvanometer.
