Assertion : In the purely resistive element of a series $LCR$ $AC$ circuit,the maximum value of $rms$ current increases with an increase in the angular frequency of the applied $e.m.f$.
Reason : $I_{\max} = \frac{\varepsilon_{\max}}{Z}$,where $Z = \sqrt{R^2 + (\omega L - \frac{1}{\omega C})^2}$ and $I_{\max}$ is the peak current in a cycle.

• A
  If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
• B
  If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
• C
  If the Assertion is correct but Reason is incorrect.
• D
  If both the Assertion and Reason are incorrect.
