Question

A current of ((2/√3)) A produces a deflection of 60° in a tangent galvanometer. The reduction factor is (A) ((2/√3))A (B) 2A (C) ((2/3)) A (D) ((3/2))A

For tangent galvanometer I=K tan θ K=(I/ tan θ) K=(2 / √3/ tan 60°) K=(2/3) A

Q. A current of $(\frac{2}{3}) A$ produces a deflection of $6 0^{\circ}$ in a tangent galvanometer. The reduction factor is

$(\frac{2}{3})$ A

2A

$(\frac{2}{3})$ A

$(\frac{3}{2})$ A

For tangent galvanometer
$I = K tan θ$
$K = \frac{I}{t a n θ}$
$K = \frac{2/ 3}{t a n 6 0 ^{\circ}}$
$K = \frac{2}{3} A$

Q. A current of (3​2​)A produces a deflection of 60∘ in a tangent galvanometer. The reduction factor is

(3​2​)A

2A

(32​) A

(23​)A

For tangent galvanometer I=Ktanθ K=tanθI​ K=tan60∘2/3​​ K=32​A
