In an $A.C.$ circuit,the reactance of a coil is $\sqrt{3}$ times its resistance. The phase difference between the voltage across the coil and the current through the coil will be

• A
  $\tan^{-1}(0)$
• B
  $\tan^{-1} \left(\frac{1}{\sqrt{3}}\right)$
• C
  $\tan^{-1}(1)$
• D
  $\tan^{-1}(\sqrt{3})$
