A) 4W
B) 2W
C) 1W
D) 5W
Correct Answer: D
Solution :
[d] \[{{V}_{ab}}=6V\] \[{{V}_{ab}}={{V}_{cd}}={{V}_{ef}}\] (parallel combination) \[{{V}_{cd}}=6V\] \[I\times 4=6\] \[I\times 1.5A\] \[{{V}_{ef}}=I\times (5\times 1)\] \[6=I\times 6\] \[I\times 1A\] Power dissipated \[(5\Omega )={{I}^{2}}R\] \[={{(1)}^{2}}\times 5\] \[=5\,Watt\]You need to login to perform this action.
