    A full-wave p-n diode rectifier uses a load resistor of 1500\[\Omega \]. No filter is used. The forward bias resistance of the diode is 10\[\Omega \]. The efficiency of the rectifier is

    A)  81.2%                                  

    B)  40.6%

    C)  80.4%                                  

    D)  40.2%

    Correct Answer: C

    Solution :

     Efficiency            \[\eta =\frac{output}{input}\times 100\]              \[=\left( \frac{81.2}{1+\frac{10}{1500}} \right)\times 100\]\[=80.4%\]
