A) 0.1
B) 0.3
C) 0.6
D) None of these
Correct Answer: A
Solution :
Applying Kirchhoffs law in the given figure. At junction A \[i+{{i}_{1}}+{{i}_{2}}=1\] ...(i) For loop (1) \[-60i+(15+5){{i}_{1}}=0\] \[\Rightarrow \] \[{{i}_{1}}=3i\] ...(ii) For loop (2) \[-(15+5){{i}_{1}}+10{{i}_{2}}=0\] \[\Rightarrow \] \[{{i}_{2}}=2{{i}_{1}}=6i\] ...(iii) On solving Eqs. (i), (ii) and (iii), we get \[i=0.1\text{ }A\]
