  • question_answer
    Ten wires each of resistance\[1\,\Omega \] are connected in parallel, then total resistance will be

    A)  \[10\,\,\Omega \]                                          

    B)  \[1\,\,\Omega \]

    C)  \[0.1\,\,\Omega \]                                        

    D) \[0.001\,\,\Omega \]

    Correct Answer: C

    Solution :

                    In parallel\[\frac{1}{R}=\frac{1}{1}+...10\]times \[\frac{1}{R}=10\] \[\Rightarrow \]               \[R=\frac{1}{10}=0.1\,\Omega \]
