For the circuit of FIGURE EX32.32,

a. What is the resonance frequency, in both rad/s and Hz?

b .Find and at resonance.

c. How can be larger than ? Explain.

a.

b.

c. and have opposite phases

We have been given values of

Inductance ()=

Capacitance() =

We need to find out the resonant frequency , (in Hz) and (in rad/s)

In a series LCR Circuit, the resonant frequency , is given by

Given ;

Now,

We need to find out and at resonance

Resonance frequency () =

Voltage =

We need to explain how can be larger than

The voltage drop across the inductor can be greater than the applied voltage of ac because as and have opposite phases. Therefore, or may be greater than or
