Question : 46 of 50

Marks: +1, -0

Solution:

Concept: A tangent galvanometer measures current using the tangent of the deflection angle.

Explanation: The current (

I

) in a tangent galvanometer is directly proportional to the tangent of the deflection angle (

\theta

), with

K

being the galvanometer constant. The formula is

I = K \tan \theta

Answer: B. current
