    When reading of an ammeter is 10A. The peak value of current is:

    A)  \[\frac{10}{\sqrt{2}}A\]        

    B)  \[\frac{5}{\sqrt{2}}A\]

    C)  \[20\sqrt{2}A\]

    D)  \[10\sqrt{2}A\]

    Correct Answer: D

    Solution :

    Ammeter reads the roots mean square value of current \[({{i}_{rms}})\]and \[{{i}_{rms}}\] is given by \[{{i}_{rms}}=\frac{{{i}_{0}}}{\sqrt{2}}\] Where,   \[{{i}_{0}}=\]peak value of current \[{{i}_{0}}=\sqrt{2}\times {{i}_{rms}}\] Here,          \[{{i}_{rms}}=10A\] \[{{i}_{0}}=\sqrt{2}\times 10A=10\sqrt{2}A.\]
