  • question_answer
    Two resistors of resistance \[{{R}_{1}}\] and \[{{R}_{2}}\] having \[{{R}_{1}}>{{R}_{2}}\] are connected in parallel. For equivalent resistance \[R\], the correct statement is [CPMT 1978; KCET (Med.) 2000]

    A)                    \[R>{{R}_{1}}+{{R}_{2}}\]

    B)                                      \[{{R}_{1}}<R<{{R}_{2}}\]

    C)                    \[{{R}_{2}}<R<({{R}_{1}}+{{R}_{2}})\]                    

    D)            \[R<{{R}_{1}}\]

    Correct Answer: D

    Solution :

       Equivalent resistance of parallel resistors is always less than any of the member of the resistance system.
