  • question_answer
    The color code of a resistance is given below                                                           [NEET 2020]
    The values of resistance and tolerance, respectively, are

    A)  \[47\,\,k\Omega ,\,\,10%\]          

    B)       \[4.7\,\,k\Omega ,\,\,5%\]

    C)  \[470\,\,\Omega ,\,\,5%\]

    D)       \[470\,\,k\Omega ,\,\,5%\]

    Correct Answer: C

    Solution :

    [c] According to colour coding
    Yellow   Violet    Brown   Gold
                 4            7           1        5%
    So, \[R=47\times {{10}^{1}}\pm 5%\]
    \[R=470\pm 5%\text{ }\Omega \]
