    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, \[{{X}_{L}}=\omega L=2\pi f\,L=0\] Therefore,\[Z=R=10\Omega \]
