## Voltage Divider and Current Divider

In electronics, the voltage divider rule is a simple and most important electronic circuit , which is used to change a large voltage into a small voltage. The best example for a voltage divider is two resistors are connected in series. Generally, these dividers are used to reduce the magnitude of the voltage or to create reference voltage and also used at low frequencies as a signal attenuator. For DC and relatively low frequencies, a voltage divider may be appropriately perfect if made only of resistors; where the frequency response is required over a wide range. Definition: In the field of electronics, a voltage divider is a basic circuit, used to generate a part of its input voltage like an output.

Voltage Divider and Current Divider are the most common rules applied in practical electronics. As you know, there are two types of combinations in a circuit, they are series and parallel connections. Parallel circuits are also known as current divider circuits because, in these circuits, the current is divided through each resistor. Whereas, series circuits are known as voltage divider circuits because here voltage is divided across all the resistors. Voltage division rule and current division rule are necessary to understand voltage and the current flowing through each resistor. These division rules are used in most common electronic devices. In order to send a current through an electric conductor , an electromotive force has to be applied.

## Answers to Problems - The Current Divider

A parallel circuit acts as a current divider as the current divides in all the branches in a parallel circuit, and the voltage remains the same across them. The current division rule determines the current across the circuit impedance. The current division is explained with the help of the circuit shown below:.

### voltage divider rule pdf

A parallel circuit is often called a current divider for its ability to proportion—or divide—the total current into fractional parts. Knowing that branch currents add up in parallel circuits to equal the total current, we can arrive at total current by summing 6 mA, 2 mA, and 3 mA:. The final step, of course, is to figure total resistance. Once again, it should be apparent that the current through each resistor is related to its resistance, given that the voltage across all resistors is the same. Rather than being directly proportional, the relationship here is one of inverse proportion. For example, the current through R 1 is twice as much as the current through R 3 , which has twice the resistance of R 1. If we were to change the supply voltage of this circuit, we find that surprise!

Откуда вам это известно. - Это не имеет отношения к делу. Нуматака выдержал паузу.

О чем вы говорите. Стратмор вздохнул. - У Танкадо наверняка была при себе копия ключа в тот момент, когда его настигла смерть. И я меньше всего хотел, чтобы кто-нибудь в севильском морге завладел ею. - И вы послали туда Дэвида Беккера? - Сьюзан все еще не могла прийти в.  - Он даже не служит у .

За три десятилетия он перехитрил, превзошел и задавил рекламой всех своих японских конкурентов, и теперь лишь один шаг отделял его от того, чтобы превратиться еще и в гиганта мирового рынка. Он собирался совершить крупнейшую в своей жизни сделку - сделку, которая превратит его Нуматек корпорейшн в Майкрософт будущего. При мысли об этом он почувствовал прилив адреналина.

ГЛАВА 87 Веспа выехала в тихий переулок Каретерра-де-Хуелва. Еще только начинало светать, но движение уже было довольно оживленным: молодые жители Севильи возвращались после ночных пляжных развлечений. Резко просигналив, пронесся мимо мини-автобус, до отказа забитый подростками. Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду. Метрах в пятистах сзади в снопе искр на шоссе выкатило такси.

Горя желанием выяснить, поддается ли Цифровая крепость взлому, Стратмор принял решения обойти фильтры. В обычных условиях такое действие считалось бы недопустимым. Но в сложившейся ситуации никакой опасности в загрузке в ТРАНСТЕКСТ этой программы не было, потому что коммандер точно знал, что это за файл и откуда он появился. - Несмотря на все мое уважение к вам, сэр, - продолжал настаивать Чатрукьян, - мне никогда еще не доводилось слышать о диагностике, в которой использовалась бы мутация… - Коммандер, - перебила его Сьюзан, которая не могла больше ждать.  - Мне действительно нужно… На этот раз ее слова прервал резкий звонок мобильного телефона Стратмора.

Беккер выжал из него все, что мог, и отчаянно боялся, что мотоцикл заглохнет в любую минуту. Нельзя было даже оглянуться: такси остановится в любой момент и снова начнется стрельба. Однако выстрелов не последовало.

По другой стороне улицы, оставаясь невидимым, шел человек в очках в тонкой металлической оправе. ГЛАВА 27 Тени в зале шифровалки начали удлиняться и терять четкость. Автоматическое освещение постепенно становилось ярче. Сьюзан по-прежнему молча сидела за компьютером, ожидая вестей от Следопыта. Поиск занял больше времени, чем она рассчитывала.

В уране девяносто два протона и сто сорок шесть нейтронов, но… - Нам нужна самоочевидная разница, - подсказала Мидж.  - У Танкадо сказано: главная разница между элементами. - Господи Иисусе! - вскричал Джабба.  - Откуда нам знать, что для Танкадо было главной разницей.

Болван этот полицейский. Ну только подумайте. Усадить человека моих лет на мотоцикл.
