A) 5 A
B) 0 A
C) 3 A
D) 4 A
Correct Answer: A
Solution :
The current in the circuit are assumed as shown in the figure. Applying KVL along the loop ABDA, we get \[-6{{i}_{1}}-3{{i}_{2}}+15=0\,\,\,\,\,\,or\,\,\,\,\,2{{i}_{1}}+{{i}_{2}}=5\,\,\,\,\,\] ? (i) Applying KVL along the loop BCDB, we get \[-3({{i}_{1}}-{{i}_{2}})-30+3{{i}_{2}}=0\,\,\,\,\,or\,\,\,-{{i}_{1}}+2{{i}_{2}}=10\] ... (ii) Solving equations (i) and (ii) for \[{{i}_{2}}\], we get\[{{i}_{2}}\,\,=\,\,5A\].You need to login to perform this action.
