Assertion: The tangent galvanometer can be made more sensitive by increasing the number of turns of its coil.
Reason: Current through galvanometer is proportional to the number of turns of coil.

(A) : The tangent galvanometer can be made more sensitive by increasing the number of turns of its coil. (R) : For a given P.D current through galvanometer is inversely proportional to the number of turns of coil.

The moving coil galvanometer can be made more sensitive by

Decreases in number of turns of coil in tangent galvanometer is

A moving coil galvanometer has number of turns 'N' in its coil. Then its sensitivity is in proportional to :-

Two tangent galvanometers differ only in number of turns in the coil. For same current deflection in them is 45^@ and 35^@ respectively. Find ratio of number of turns of galvanometers.

A tangent galvanometer is connected directly to an ideal battery. If the number of turns in the coil is doubled, the deflection will
