A) 1.6 A
B) 1.8 A
C) 1.25 A
D) 1.0 A
Correct Answer: B
Solution :
Applying Kirchhoff?s law for the loops (1) and (2) as shown in figure For loop (1)
\[-2{{i}_{1}}-2({{i}_{1}}-{{i}_{2}})+4=0\] Þ \[2{{i}_{1}}-{{i}_{2}}=2\] ?(i) For loop (2) \[-2({{i}_{1}}-{{i}_{2}})+4{{i}_{2}}-6=0\] Þ \[-{{i}_{1}}+3{{i}_{2}}=3\] ?(ii) On solving equation (i) and (ii) \[{{i}_{1}}=1.8A\].
