    A DC circuit contains\[10\,\Omega \]. of resistance in series with 10 H coil. The impedance of the circuit is

    A)  \[10\,\Omega \]             

    B)  \[20\,\Omega \]

    C)  \[1\,\Omega \]              

    D)  zero

    Correct Answer: A

    Solution :

     In a DC circuit \[{{X}_{L}}=\omega L=2\pi fL=0\] Therefore \[Z=R=10\,\Omega \]
