  • question_answer
                    In a circuit inductance L and capacitance C are connected as shown in figure. \[{{A}_{1}}\] and \[{{A}_{2}}\] are ammeters. When key K. is pressed to complete the circuit, then just after closing key (K), the reading of current will be:                                                                                                                                                                                                

    A)                 zero in both \[{{A}_{1}}\] and \[{{A}_{2}}\]                                                               

    B)                 maximum in both \[{{A}_{1}}\] and \[{{A}_{2}}\]

    C)                 zero in \[{{A}_{1}}\] and maximum in \[{{A}_{2}}\]

    D)                         maximum in \[{{A}_{1}}\] and zero in \[{{A}_{2}}\]

    Correct Answer: D

    Solution :

                    Initially there is no DC current in inductive circuit and maximum DC current in capacitive circuit. Hence, the current is zero in \[{{A}_{2}}\] and maximum in \[{{A}_{1}}\].
