# 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

See the step by step solution

## Part (a) Step 1 : Given information

We have been given values of

Inductance ()=

Capacitance() =

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

## Part(a) Step 2 : Detailed solution

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

Given ;

Now,

## Part (b) Step 1: Given information

We need to find out and at resonance

Resonance frequency () =

Voltage =

## Part (c) Step 1:  Given information

We need to explain how can be larger than

## Part(c) Step 2: Explanation

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
