    In the circuit shown below, the current flowing through the circuit is

    A) 0.50A                           

    B) 0.25A

    C) 1.00A               

    D) 1.50A

    Correct Answer: C

    Solution :

    [c] \[2\Omega ,4\Omega \] and \[2\Omega ,\] are in series and their resultant \[(=8\Omega ,)\] is in parallel with 8 \[\Omega ,\]which gives rise to \[4\,\Omega ,\]. Next, \[2\Omega ,\,\,4\,\Omega ,\]and\[2\Omega ,\]are in series and their resultant \[\left( =8\text{ }\Omega  \right)\]is in parallel with \[8\Omega \], which again gives rise to \[4\Omega \]. Now, \[3\Omega ,\,\,4\Omega \]and \[2\Omega ,\] are in series and their resultant is \[9\Omega ,\] \[\therefore \,\,I=\frac{9V}{9\Omega }=1A\]
