A) 0.1
B) 0.3
C) 0.6
D) none of these
Correct Answer: A
Solution :
All the resistances are in parallel order, so voltage across them will be equal. \[\therefore \] \[60\,I=(15+5)\,{{I}_{1}}\] \[\Rightarrow \] \[60I=20\,{{I}_{1}}\] \[\Rightarrow \] \[{{I}_{1}}=3\,\,I\] ... (i) Again \[(15+5)\,{{I}_{1}}=10\,(1-I-{{I}_{1}})\] \[\Rightarrow \] \[2{{I}_{1}}=1-I-{{I}_{1}}\] \[\Rightarrow \] \[2\,(3l)=1-I-3I\] \[\Rightarrow \] \[6I+4I=1\] \[\Rightarrow \] \[10I=1\] \[\therefore \] \[I=\frac{1}{10}=0.1\,A\]You need to login to perform this action.
