  • question_answer
    Ten wires each of resistance 1 ohm are connected in parallel, then total resistance will be:

    A)  10\[\Omega \]                

    B)         1\[\Omega \]

    C)  0.1\[\Omega \]               

    D)         0.0010\[\Omega \]

    Correct Answer: C

    Solution :

    In parallel \[\frac{1}{R}=\frac{1}{1}+\]?10 times                  \[\frac{1}{R}=10\]          \[\Rightarrow R\frac{1}{10}=0.1\,\text{ohms}\]
