Problem

A series circuit has

R = 50\,\Omega

,

L = 0.20\,\text{H}

and

C = 100\,\mu\text{F}

. It is connected to an a.c. source of

100\,\text{V}

(rms). If

P_1

is the average power consumed at

50\,\text{Hz}

and

P_2

at

100\,\text{Hz}

, the ratio

\dfrac{P_2}{P_1}

is closest to a)

1.0

b)

4.2

c)

0.24

d)

0.48
