The relation between voltage sensitivity (\[{{\sigma }_{V}}\]) and current sensitivity \[({{\sigma }_{i}})\] of a moving coil galvanometer is (Resistance of Galvanometer = G)                                  [CPMT 2001]

A.            \[\frac{{{\sigma }_{i}}}{G}={{\sigma }_{V}}\]             
B.            \[\frac{{{\sigma }_{_{V}}}}{G}={{\sigma }_{i}}\]
C.            \[\frac{G}{{{\sigma }_{V}}}={{\sigma }_{i}}\]             
D.            \[\frac{G}{{{\sigma }_{i}}}={{\sigma }_{V}}\]
Answer» B.            \[\frac{{{\sigma }_{_{V}}}}{G}={{\sigma }_{i}}\]
