A Transformer is a static apparatus, with no moving parts, which transforms electrical power from one circuit to another with changes in voltage and current and no change in frequency. There are two types of transformers classified by their function: Step up Transformer and Step down Transformer.

Difference between Step-up and Step-down Transformer

Transformers do what their name implies—they transform voltages from one value to another The term voltage is used rather than emf, because transformers have internal resistance. For example, many cell phones, laptops, video games, and power tools and small appliances have a transformer built into their plug-in unit like that in Figure 1 that changes V or V AC into whatever voltage the device uses. Transformers are also used at several points in the power distribution systems, such as illustrated in Figure 2. Power is sent long distances at high voltages, because less current is required for a given amount of power, and this means less line loss, as was discussed previously. Figure 1. The plug-in transformer has become increasingly familiar with the proliferation of electronic devices that operate on voltages other than common V AC.

The main difference between step-up and step-down transformer is that, step-up transformer increases the voltage whereas a step-down transformer decreases the voltage. The secondary voltage of step-up transformer is more than that of its primary voltage whereas the secondary voltage of step-down transformer is less than its primary voltage. In fact, these two terms, i. From construction and design point of view, there is no difference between step-up and step-down transformer. A given transformer can be used as step-up or step-down transformer. If the HV High Voltage winding is connected to supply main and LV low voltage winding to load, the transformer works as Step-down transformer. This is because, the transformer is delivering the power at a decreased voltage at secondary terminal.

Step-Up Transformer Vs Step-down Transformer: What Is The Difference?

A transformer in which the output secondary voltage is greater than its input primary voltage is called a step-up transformer. The step-up transformer decreases the output current for keeping the input and output power of the system equal. Considered a step-up transformer shown in the figure below. The number of turns on the secondary of the transformer is greater than that of the primary, i. Thus the voltage turn ratio of the step-up transformer is The primary winding of the step-up transformer is made up of thick insulated copper wire because the low magnitude current flows through it.

Equality of voltage and current between the primary and secondary sides of a transformer, however, is not the norm for all transformers. Notice how the secondary voltage is approximately ten times less than the primary voltage 0. What we have here is a device that steps the voltage down by a factor of ten and current up by a factor of ten:. Turns ratio of yields primary: secondary voltage ratio and primary: secondary current ratio. This is a very useful device, indeed. With it, we can easily multiply or divide voltage and current in AC circuits.

Беккер, спотыкаясь и кидаясь то вправо, то влево, продирался сквозь толпу. Надо идти за ними, думал. Они знают, как отсюда выбраться. На перекрестке он свернул вправо, улица стала пошире. Со всех сторон открывались ворота, и люди вливались в поток.

АНБ является счастливым обладателем алгоритма Цифровой крепости, просто мы не в состоянии его открыть. Сьюзан не могла не восхититься умом Танкадо. Не открыв своего алгоритма, он доказал АНБ, что тот не поддается дешифровке. Стратмор протянул Сьюзан газетную вырезку. Это был перевод рекламного сообщения Никкей симбун, японского аналога Уолл-стрит джорнал, о том, что японский программист Энсей Танкадо открыл математическую формулу, с помощью которой можно создавать не поддающиеся взлому шифры. Формула называется Цифровая крепость, говорилось в заметке, и доступна для ознакомления в Интернете. Программист намеревался выставить ее на аукционе и отдать тому, кто больше всех заплатит.

Горячий воздух снизу задувал под юбку. Ступеньки оказались очень скользкими, влажными из-за конденсации пара. Она присела на решетчатой площадке. - Коммандер. Стратмор даже не повернулся. Он по-прежнему смотрел вниз, словно впав в транс и не отдавая себе отчета в происходящем. Сьюзан проследила за его взглядом, прижавшись к поручню.

Готова спорить на любые деньги, что он. Чутье мне подсказывает.  - Второе, что никогда не ставилось под сомнение, - это чутье Мидж.
