Previously in Lesson 4 , it was mentioned that there are two different ways to connect two or more electrical devices together in a circuit. They can be connected by means of series connections or by means of parallel connections.

Series - Parallel Circuits
Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected. In a series circuit , the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit , all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together. In the case of a parallel configuration, each resistor has the same potential drop across it, and the currents through each resistor may be different, depending on the resistor.
The crucial difference between series and parallel circuit exist on the basis of orientation of the components in the circuit. In a series circuit, the multiple components are connected in a cascaded manner i. While in a parallel circuit, the multiple components are connected in head to head and tail to tail orientation. In the series circuit, the components in the circuit are connected one after the other or we can say in a cascaded fashion. More specifically we can say that a series circuit allows the connection in a manner that tail of one component is directly connected to the head of the other and so on corresponding to the two ends of the battery. As we can clearly see that the components are cascaded in a single line, thus same current, I will flow through all the resistors of the series network.
Total power in a parallel circuit is the sum of the power consumed on the individual branches. Chapter 07 Series-Parallel Circuits Source And now c we are left with R in parallel with R 3. What would happen if they were wired in series? Some circuits include both series and parallel parts.

With simple series circuits , all components are connected end-to-end to form only one path for the current to flow through the circuit:. With simple parallel circuits , all components are connected between the same two sets of electrically common points, creating multiple paths for the current to flow from one end of the battery to the other:. With each of these two basic circuit configurations, we have specific sets of rules describing voltage, current, and resistance relationships. Instead, we will have to identify which parts of that circuit are series and which parts are parallel, then selectively apply series and parallel rules as necessary to determine what is happening. Take the following circuit, for instance:. This circuit is neither simple series nor simple parallel.
More complicated electrical circuits, such as those found in radios and computers, have intricate circuits that allow them to perform complicated functions, process.
What is a Series-Parallel Circuit?
We define the properties of parallel and complex circuits. We examine how to find the total voltage, current, and resistance of parallel and complex circuits. We also use a V. Plan and carry out an investigation of the relationship between voltage, current, and power for direct current circuits.

In this section we look at how to analyse circuits which contain resistors in series and parallel combinations. The figure below shows a basic circuit which contains a series-parallel combination of resistors. The total circuit resistance from point A to C is the series resistor R1 in combination with the parallel components. Also the resistors R3 , R2 and R1 form a parallel combination. It is also clear that the two parallel combinations are in series with one another.

Казалось, Стратмор ее не слышал. - В последние несколько лет наша работа здесь, в агентстве, становилась все более трудной. Мы столкнулись с врагами, которые, как мне казалось, никогда не посмеют бросить нам вызов. Я говорю о наших собственных гражданах. О юристах, фанатичных борцах за гражданские права, о Фонде электронных границ - они все приняли в этом участие, но дело в другом.
- Мне нужно закончить разговор. - Он повернулся и направился к своему кабинету. Сьюзан открыла рот, но слова застряли у нее в горле.
Молодой человек, - вскипел Стратмор, - я не знаю, откуда вы черпаете свою информацию, но вы переступили все допустимые границы. Вы сейчас же отпустите мисс Флетчер, или я вызову службу безопасности и засажу вас в тюрьму до конца ваших дней. - Вы этого не сделаете, - как ни в чем не бывало сказал Хейл.
