    The maximum voltage in DC circuit is 282 Volt. The effective voltage in AC circuit will be

    A)  200 V            

    B)  300 V

    C)  400 V            

    D)  564 V

    Correct Answer: B

    Solution :

     Maximum voltage is AC circuit \[{{V}_{0}}=282V\] \[V=\frac{{{V}_{0}}}{\sqrt{2}}=\frac{282}{\sqrt{2}}\] \[V=\frac{282}{1.41}=200\,V\] \[V=200V\]
