In the given circuit, \( R \) is a pure resistor, \( L \) is a pure inductor, \( S \) is a \( 50 \mathrm{~V}, 50 \mathrm{~Hz} \mathrm{AC} \) source and \( A \) is an \( \mathrm{AC} \) ammeter. With either \( K_{1} \) or \( K_{2} \) alone closed, the am meter reading is \( I \). If the source is changed to \( 100 \mathrm{~V}, 100 \mathrm{~Hz} \), then ammeter reading with \( K_{1} \) alone closed and with \( K_{2} \) alone closed
\( \mathrm{P} \) will be respectively
(a) \( I, \frac{I}{2} \)
(b) \( I, 2 I \)
(c) \( 2 I, I \)
(d) \( 2 I, \frac{I}{2} \)
