A) 0.5 A
B) 0.6 A
C) 1.5 A
D) 2.0 A
Correct Answer: B
Solution :
Let \[i\] be the current through arm ADC. Then current through arm \[ABC=(2.1-i).\]As there is no deflection in the galvanometer, hence \[(20+5)i=(8+2)\]\[(2.1-i)\] or \[25\,i=21-10\,i\]or \[35\,i=21\] \[i=21/35=3/5=0.6\,A\] Hence, the correction option is (b).You need to login to perform this action.
