    Find the value of current I in the given circuit

    A)  1 A              

    B)  4 A

    C)  5 A              

    D)  None of these

    Correct Answer: A

    Solution :

     The resistance of the circuit \[\frac{1}{R}=\frac{1}{(2+2+2)}+\frac{1}{2}=\frac{2}{3}\] \[R=1.5\,\Omega \] \[I=\frac{E}{R}=\frac{1.5}{1.5}=1A\]
