    In a LR circuit \[1.67\times {{10}^{14}}Hz\]and \[9.10\times {{10}^{14}}Hz\]. If the circuit has an alternating emf of 220 volt 50 cycles per sec. The impedance and current in the circuit will be :

    A)  50\[6\times {{10}^{14}}Hz\], 4.4A                           

    B)  40.4\[4\times {{10}^{14}}Hz\], 5A

    C)  3.07\[0.4A{{m}^{2}}\], 6.0A                       

    D)  11.4\[1.6A{{m}^{2}}\], 17.5A

    Correct Answer: A

    Solution :

    The impedance of circuit is given by                 \[6\hat{i}-6\hat{j}+3\hat{k}\]                 \[18\hat{i}-13\hat{j}+2\hat{k}\]                 \[4\hat{i}-13\hat{j}+6\hat{k}\]  The current in the circuit is given by                 \[6\hat{i}-2\hat{j}+8\hat{k}\]
