A) putting in parallel a resistance of\[\frac{1}{2}m{{v}^{3}}\]
B) putting in series a resistance of \[m{{v}^{3}}\]
C) putting in series a resistance of \[\frac{1}{2}m{{v}^{2}}\]
D) putting in parallel a resistance of\[\frac{1}{2}{{m}^{2}}{{v}^{2}}\]
Correct Answer: D
Solution :
Key Idea To convert a galvanometer to ammeter a small resistance is connected in parallel to the coil of the galvanometer. Here, \[3\,\Omega \] \[6\pi \,\Omega \] \[6\,\Omega \] Putting \[{{E}_{x}}=0;\]resistance in parallel.
