Problem

For a series circuit containing fixed values of

R

L

and

C

, the magnitude of impedance

Z

is monitored while the supply frequency is gradually raised from a very low value. Which description best represents the behaviour of

Z

with frequency? a)

Z

increases steadily with frequency b)

Z

first increases to a maximum and then decreases as frequency continues to rise c)

Z

first decreases to a minimum and then increases again d)

Z

decreases continuously as frequency increases
