  • question_answer
    The current in the following circuit is              [CBSE PMT 1997]

    A)            \[\frac{1}{8}A\]

    B)                    \[\frac{2}{9}A\]

    C)                    \[\frac{2}{3}A\]

    D)                    \[1A\]

    Correct Answer: D

    Solution :

                 Resistance across the battery is            \[\frac{1}{{{R}_{p}}}=\frac{1}{3}+\frac{1}{6}=\frac{2+1}{6}=\frac{3}{6}\] Þ \[{{R}_{p}}=2\Omega \]Þ \[I=\frac{2}{2}=1\,A\]
