Assertion: Reduction factorof a tangent galvanometer helps in reducing deflection of current.
Reason: As reduction factor increases with increase of current.
Options:
Answer:
C
Solution:
In tangent galvanometer current is directly proportional to the deflection and reduction factor helps in reducing reflection of the current.
The Reduction factor doesn't depend on current but on the construction of the instrument.
The assertion is true but the Reason is false.
