Cách đọc trị số điện trở bằng vạch màu .
Điện trở là gì , nhiều chủng loại điện trở và công thức tính điện trở
Nguồn điện là gì ? dòng điện là gì ? nguồn điện 1 chiều và nguồn điện xoay chiều
Do điện trở có hình dạng và kích thước nhỏ nên việc ghi những số lượng trên đó rất khó . Do đó người ta vẽ những vạch màu trên đó để chỉ ra giá trị của điện trở . Vậy để đọc được điện trở ta phải vẽ những bảng mã màu như sau :
Đen : 0 , Nâu : 1 , Đỏ : 2 , Cam :3 , Vàng : 4 , Lục : 5 , Lam : 6 , Tím : 7 , Xám : 8 , Trắng : 9 , Nhũ vàng : 10-1 sai số 5% , Nhũ bạc : 10-2 sai số 10% , không màu : sai số 20% .
Hướng dẫn cách đọc vạch màu điện trở dễ nhớ .
Đen không , nâu một , đỏ hai
Cam ba , vàng bốn , Lục Năm
Lam sáu , Tím bảy , Xám Tám
Chín thường trắng tinh .
Cách đọc điện trở 4 vạch màu .
Vạch màu thứ nhất: Chỉ giá trị hàng trăm trong giá trị điện trở
Vạch màu thứ hai: Chỉ giá trị hàng cty trong giá trị điện trở
Vạch màu thứ ba: Chỉ thông số nhân với giá trị số mũ của 10 dùng nhân với giá trị điện trở
Vạch màu thứ 4: Chỉ giá trị sai số của điện trở
Ví dụ 1 : trên thang điện trở có những vạch màu lần lượt như sau : vàng , tím , cam , nhũ vàng = 47 x 103 = 47000Ω =47kΩ .
Ví dụ 2 : trên điện trở lần lượt : Lục , Lam , nhũ vàng , nhũ bạc = 56/10 = 5,6 Ω .
Ví dụ 3 : Trên điện trở lần lượt : nâu , xám , đen , nhũ vàng = 18 x 100 = 18Ω
Cách đọc điện trở 5 vạch màu .
Điện trở 5 vạch màu là điện trở có độ đúng chuẩn cao sai số nhỏ chỉ 1% tới 2% . thường được lắp ráp trong những thiết bị điện tử tiêu dùng để đo lường quốc tế ví như đồng hồ đeo tay vạn năng hay máy hiện sóng osillo …
Cách đọc như sau :
Vạch màu thứ nhất: Chỉ giá trị hàng trăm trong giá trị điện trở
Vạch màu thứ hai: Chỉ giá trị hàng trăm trong giá trị điện trở
Vạch màu thứ ba: Chỉ giá trị hàng cty trong giá trị điện trở
Vạch màu thứ tư: Chỉ thông số nhân với giá trị số mũ của 10 dùng nhân với giá trị điện trở
Vạch màu thứ năm : Chỉ giá trị sai số của điện trở
Ví dụ 1 : trên thang điện trở có những vạch mầu lần lượt
Cam , cam , đen , đỏ , nâu = 330x 102 = 33000Ω = 33kΩ
Ví dụ 2 : trên điện trở có những vạch màu lần lượt
Đỏ , tím , đen , đen , nâu = 270 x 100 = 270 Ω .
Cách đọc điện trở dán , điện trở hiệu suất .
Trên thân điện trở có ghi ví như : abc nghĩa là ab x 10c = xΩ
Vi dụ : trên thân điện trở ghi 473 nghĩa là 47 x 103 = 47000 Ω = 47kΩ
Hoặc trên thân điện trở có ghi :
22R nghĩa là 22Ω
5R6 nghĩa là 5,6Ω
0R9 nghĩa là 0,9Ω
50k nghĩa là 50KΩ
1K5 nghĩa là một trong,5KΩ
20M nghĩa là 20 MΩ
Cách ghép những điện trở .
Ghép tiếp nối đuôi nhau : khi ta muốn tăng trị số của điện trở thì ta ghép những điện trở nhỏ lại với nhau .
Ghép tuy nhiên tuy nhiên : khi ta muốn giảm trị số điện trở thì ta ghép tuy nhiên tuy nhiên những điện trở thành phần lại với nhau .

Read the following passage on climate change, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
One day in 1924, five men who were camping in the Cascade Mountains of Washington saw a group of huge apelike creatures coming out of the woods. They hurried back to their cabin and locked themselves inside. While they were in, the creatures attacked them by throwing rocks against the walls of the cabin.After several hours, these strange hairy giants went back into the woods.
After this incident the men returned to the town and told the people of their adventure. However, only a few people accepted their story. These were the people who remembered hearing tales about footprints of an animal that walked like a human being.
The five men, however, were not the first people to have seen these creatures called Bigfoot. Long before their experience, local Native Americans were certain that a race of apelike animals had been living in the neighboring mountain for centuries. They called these creatures Sasquatch.
In 1958, workmen, who were building a road through the jungles of Northern California often found huge footprints in the earth around their camp.
Then in 1967, Roger Patterson, a man who was interested in finding Bigfoot went into the Northern California jungles with a friend. While riding, they were suddenly thrown off from their horses. Patterson saw a tall apelike animal standing not far away. He managed to shoot seven rolls of film of the hairy creature before the animal disappeared in the hushes. when Patterson's film was shown to the public, not many people believed his story. In another incident, Richard Brown, a music teacher and also an experienced hunter spotted a similar creature. He saw the animal clearly through the telescopic lens of his rifle. He said the creature looked more like a human than an animal.
Later many other people also found deep footprints in the same area. In spite of regular reports of sightings and footprints, most experts still do not believe that Bigfoot really exists.
Question:Who were the first people to have seen these apelike creatures before the five campers?

Mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions:
The increase in international business and in foreign investment has created a need for executives with knowledge of foreign language and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level in negotiation in an international arena as have their foreign counterparts.
Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. Involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of negotiation.
In many international negotiations business abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that Americans represents a large multimillion–dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role became that of and impersonal purveyor of information and cash, the image that succeeds only in underming the negotiation.
In studies of American negotiators abroad, several traits have been identified that may serve to confirm that stereotypical perception, while subverting the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on that part of Amarican negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator.
Clearly, perceptions and differences in values affect the outcomes of negotiation and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50:
There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them. The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates. There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant – yet slow – motion. The plates may move away from or toward other plates. In some cases, they collide violently with the plates adjoiningthem. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.
Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.
Since most of the Earth’s surface is water, numerous earthquakes happen beneath the planet’s oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousands of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height. Minutes later, the tsunami arrives. A large tsunami – one more than ten meters in height – can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of people.
