    In an A.C. circuit the potential difference across inductance and resistance joined in series are respectively 12 V and 16 V. The total potential difference across the circuit is:

    A)  20 V                                     

    B)  10 V

    C)  15 V                                     

    D)  5 V

    Correct Answer: A

    Solution :

                                                                     Here:  \[{{V}_{L}}=12V,{{V}_{R}}=16V\] The net potential difference across the circuit is given by   \[E{{V}^{2}}={{V}_{L}}^{2}+{{V}_{R}}^{2}={{(12)}^{2}}+{{(16)}^{2}}\] \[EV=\sqrt{{{(12)}^{2}}+{{(16)}^{2}}}=\sqrt{400}\] \[EV=20V\]
