state gov RPSC 2nd Grade Senior Teacher Mock Test Series 2025 Physics Moving Charges and Magnetism The Moving Coil Galvanometer
Consider a moving coil galvanometer (MCG) :
A : The torsional constant in moving coil galvanometer has dimensions [ML2T–2]
B : Increasing the current sensitivity may not necessarily increase the voltage sensitivity.
C : If we increase 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 galvanometer.
E : Current sensitivity of MCG depends inversely on number of turns of coil.
