Question
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.
- If both assertion and reason are true and the reason is the correct explanation of the assertion.
- If both assertion and reason are true but reason is not the correct explanation of the assertion.
- If assertion true but reason is false.
- If the assertion and reason both are false.
The correct answer is: If both assertion and reason are true but reason is not the correct explanation of the assertion.
In tangent galvanometer the current through the coil is given by 
Þ 
i.e. by reducing its radius or by increasing number of turns of coil we can increase the sensitivity of tangent galvanometer.
