    In an AC circuit, the potential differences across an inductance and a resistance connected in series are respectively 16V and 20V. The total potential difference across the circuit is:

    A)  \[20.0\,V\]                  

    B)  \[25.6\,V\]

    C)  \[31.9\,V\]            

    D)  \[53.5\,V\]

    Correct Answer: B

    Solution :

    We have,   \[V={{({{V}^{2}}R+V_{L}^{2})}^{1/2}}\] \[={{(20\times 20+6\times 16)}^{1/2}}=25.6V\]
