In a series

R\!L

circuit,

R=30\,\Omega

and

L=0.10\,\text{H}

. When connected to a

100\,\text{V}

AC source at

50\,\text{Hz}

, the rms current is

I_1

. If the frequency is doubled to

100\,\text{Hz}

with the same supply voltage, the new rms current

I_2

is obtained. The ratio

I_2/I_1

is closest to (a)

2.00

(b)

0.50

(c)

0.63

(d)

1.00
