The sensitivity of a tangent galvanomete...

The sensitivity of a tangent galvanometer is increased if

A

Number of turn decreases

B

Number of turn increases

C

Field increases

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Sensitivity `S= (theta)/(i)= (theta)/(K tan theta)` where `K= (2RB_(H))/(mu_(0)N)`
For increasing sensitivity K should be decreased and hence number of turns should be increased
