- (A) resistance nearly 6 k Ω in series
- (B) 6 k Ω in parallel
- (C) 5 Ω in series
- (D) 6.6 k Ω in series
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Explanation:
Current flowing through the galvanometer Ig=12 μA/div × 40 div = 480 μAThe value of resistance in series to the galvanometer isR = =6.25KΩ

- Two long parallel wires X and Y, separated by a distance of 6 cm, carry currents of 5 A and 4 A, respectively, in opposite directions as shown in the figure. Magnitude of the resultant magnetic field at point P at a distance of 4 cm from wire Y is \( 3 \times 10^{-5} \) T. The value of \( x \), which represents the distance of point P from wire X, is\( \_\_\_\_\_\) cm. (Take permeability of free space as \( \mu_0 = 4\pi \times 10^{-7} \) SI units.)
