1.you are going to measure the breakdown voltage of your Zener Diode.
It is rated at 5.1 volts.
Figure L38-4 has two different setups for you.

For the setup on the Left
Total V from TPA to TPC = 9V
V used from TPA to TPB = 9V
Volts used across Zener = 5.1V
How accurate is the rating? =
For the setup on the Right
Total V from TPA to TPC = 9V
V used from TPA to TPB = 5.1V
Volts used across Zener = 3.9V (330Ω일때 기준)

Introducing Transformers and Putting It All Together
.
.
.
What we have herre is another electronc component.
Transformers are used in homes in everything from all adapters to microwaves.
트랜스포머는 사용된다. in 집에서 in 모든것에 from all어답터들부터 to 전자렌지까지.
Larger versions are vital to the supply and distribution of electric power.
You will use a miniature transformer like the one shown in Figure L60-2.
큰 버젼은 중대하다.(=vital) to 공급하는데 and 분배하는데 of 전력을.
넌 will 사용할것이다. a 미니어쳐 트랜스포머를 like the 아래 그림같은.
How a Transformer works.
Actually there are two main questions here:
■ How does a transformer work?
■ What does it transformer ?
As you saw with the speaker,
moving electrons create a magnetic field.
What was not mentioned is that the reverse is also true.
네가 봤듯이 with the 스피커에서,
이동하는 전자는 만든다. a 자기장을.
언급하지않는건 that the reverse 또한 true이다.
A moving magnetic field induces (encourages) electrons to move
in a conducting wire.
이동하는 자기장은 유도한다. (제촉한다.) 전자들을 to 이동하게끔
in a 컨덕팅 와이어 안으로.
The moving electrons in one wire
create a magnetic field that induces electrons
in a nearby wire to move as shown in Figure L60-3.
이동하는 전자 in 한개 와이어안안에서
는 만들어낸다. a 자기장을 that 유도하는 전자들을
in a 근접한 와이어에서 to 이동하기위해 as 그림처럼
Also notice that a second wire is too far away
to be influenced
by the magnetic field created in the first wire.
또한 주목해라. that a 2차 와이어는 너무 떨어져있다.
to be 영향받으려고
by the 자기장에의해 만들어진 in the 1차 와이어에서.
Animated versions of these figures
are available for viewing
at www.mhprofessional.com/computingdownload.
Pretty fancy! But better yet,
examine Figure L60-4.
It depicts how this concept is applied so neatly in electricity and electronics.
이건 표현한다. 어떻게 이 컨셉이 적용됬는지 so 깔끔하게 in 전기&전자에.
If we lay many wires next to the “primary” wire,
it will induce (encourage) a voltage
in each of the “secondary” wires.
But wait. There’s more.
If each of those secondary wires is connected as one long wire,
the voltage induced in each wire
is added to the next.
This is shown in Figure L60-5.
만약 우리가 lay하면 많은 wires를 next to the "primary" wire옆에,
이건 will 유도할것이다. a voltage를
in each of the "secondary" wires 에서.
But 기다려라. 좀더있다.
If 각각 of those 2차 와이어들이 연결되있으면 as 하나의 긴 와이어로,
그 voltage 유도된 in 각 와이어에서
는 추가된다. to the 다음으로.
이건 그림에 나타나있다.

Checking Out the Audio Transformer
Pull out the miniature audio transformer.
It should be wrapped in green.
Various colors indicate various uses.
Most likely there will be three wires on one side and only two on the other as shown
previously in Figure L60-2.
If there are only two wires from each side,
continue with the following exercise. It will
become obvious which side is primary and which
is secondary as you do the work.
The primary side has two wires. The secondary
side has three wires. The middle wire on the
secondary is referred to as the center tap. You can
clip and tape it off. We won’t use it at all.
Plug the test cord into the headphones output of
your sound card. Use the software-based volume
control to adjust the 1,000-Hz wave output to 5
mVac. Now attach the clips to the primary wires of
the transformer as shown in Figure L60-6.
Measure the output of the two outermost
secondary wires (see Table L60-1).
