    When a given coil of ohmic resistance\[100\,\Omega \]and inductive reactance\[100\sqrt{3}\,\Omega \]is connected to a 200 V DC source, the current flows in the circuit is

    A)  1A                                         

    B)  1.5 A

    C)  2A                                         

    D)  \[100\sqrt{3}\,\Omega \]

    Correct Answer: C

    Solution :

                    An inductor offer no ohmic resistance in DC circuits as frequency\[v=0\]and consequently \[{{X}_{L}}=0\].This lead to offer smaller impedance in DC circuits and subsequently greater current. In DC circuit, The current flow \[i=\frac{V}{R}=\frac{200}{100}=2A\]
