Problem

A coil of inductance

L = 0.10\,\text{H}

and resistance

R = 20\,\Omega

is to be connected in series with a capacitor so that the circuit resonates at

f = 200\,\text{Hz}

. What should be the capacitance

C

? (a)

0.63\,\mu\text{F}

(b)

6.3\,\mu\text{F}

(c)

63\,\mu\text{F}

(d)

39.8\,\mu\text{F}
