Solution

The correct option is C Directly proportional to the number of turns in the coil
The deflection of the coil of moving coil galvanometer is given by:
$θ = \frac{N i A B}{C}$

$\Rightarrow θ \propto N$ (Number of turns)

Q. Read the two statements carefully to mark the correct option out of the options given below:

Statement -1:

The tangent galvanometer can be made more sensitive by increasing the number of turns of its coil.

Statement -2:

Current through the galvanometer is proportional to the number of turns of the coil.

Q. The magnetic induction at a point distance

radius of coil)

Q. Assertion :Increasing the current sensitivity of a galvanometer necessarily increases the voltage sensitivity. Reason: Voltage sensitivity is inversely proportional to current sensitivity.

Q. Assertion :When number of turns in a coil is doubled, coefficient of self-inductance of the coil becomes 4 times. Reason: This is because self inductance is directly proportional to the square of number of turns in a coil.
