Physics Question from JEE Main 2025 · 23 January, Shift 1

Consider a moving coil galvanometer (MCG):

A : The torsional constant in moving coil galvanometer has dimensions $[ML^2 T^{-2}]$ B : Increasing the current sensitivity may not necessarily increase the voltage sensitivity. C : If we increase the number of turns ($N$) to its double ($2N$), then the voltage sensitivity doubles. D : MCG can be converted into an ammeter by introducing a shunt resistance of large value in parallel with the galvanometer. E : Current sensitivity of MCG depends inversely on the number of turns of the coil. Choose the correct answer from the options given below:
