हिन्दीA circuit when connected to an AC source of \( 12\text{ V} \) gives a current of \( 0.2\text{ A} \). The same circuit when connected to a DC source of \( 12\text{ V} \), gives a current of \( 0.4\text{ A} \). The circuit is
Correct answer · Option B
Series LR
Explanation
AC impedance \( Z = \frac{V}{I_{AC}} = \frac{12}{0.2} = 60\,\Omega \). DC resistance \( R = \frac{V}{I_{DC}} = \frac{12}{0.4} = 30\,\Omega \). Since \( Z > R \), the circuit contains a resistor and an inductor (Series LR).
