Answer & Solution

Correct Answer

(D) (A) - (II), (B) - (I), (C) - (IV), (D) - (III)

Step-by-step Solution

Detailed explanation

(A) Current sensitivity of galvanometer: \( \frac{NAB}{k} \) → (III) (B) Magnetic field at the centre of a circular coil: \( \frac{\mu_0 I}{2R} \) → (I) (C) magnetic field due to a long straight wire carrying a current: \( \frac{\mu_0 I}{2\pi R} \) → (IV) (D) Voltage sensitivity…
