## Series and 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.

Provide reasoning to explain the measurements and relationships in circuits. For your lab report, you may copy this into a word processor. But be sure to enter your answers in a different colored font. Measure the voltage of each using the voltmeter and record the voltage in a table like the one shown. Then move the batteries end to end as below to measure combined voltage.

## What is a Series-Parallel Circuit?

There are two basic ways to connect more than two circuit components or loads : series and parallel. A series circuit is two or more electrical components connected end to end. A parallel circuit is when components are connected like the rungs of a ladder. In a series circuit assuming all the loads are equivalent , the voltage is split or shared equally between the loads. Each load gets the same current amps.

Oh no! Oh, you thought it would be funny to pull one of the bulbs out, and now the whole thing has gone belly up! Every year, millions of lights go dark around the world for one critical lesson — to teach you the difference between series and parallel circuits! The simplest of circuits, powering a light bulb with a battery. Say you have a strand of lights, connected one after the other. If you viewed this in a circuit, it would look something like this:.

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. Identify a series and parallel circuit, state the rules for series circuits, apply the rules to a circuit and calculate resistance, explain why and apply to more complex circuits. If the circuit components are connected end to end to form a single loop it is a series-circuit Remember that current is the rate at which electrons move through the circuit.

Figure 3 shows two volt batteries connected in parallel. The important things to note about a parallel connection are: 1) The battery pack voltage is the same.

## 10.3: Resistors in Series and Parallel

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.

High-wattage volt lamps may be purchased from recreational vehicle RV and boating supply stores. Common sizes are 25 watt and 50 watt. Begin this experiment by connecting one 6-volt battery to the lamp. The lamp, designed to operate on 12 volts, should glow dimly when powered by the 6-volt battery.

This section will go into more depth on series, parallel and series-parallel connections. The purpose of this section is to explain why certain connections are utilized, how to set up to your desired connection, as well as going over what is the most beneficial connection to utilize based on your situation. Strictly parallel connections are mostly utilized in smaller, more basic systems, and usually with PWM Controllers, although they are exceptions. Connecting your panels in parallel will increase the amps and keep the voltage the same.

Сэр? - Беккер легонько потормошил спящего.  - Простите, сэр… Человек не шевельнулся. Беккер предпринял очередную попытку: - Сэр. Старик заворочался. - Qu'est-ce… quelle heureest… - Он медленно открыл глаза, посмотрел на Беккера и скорчил гримасу, недовольный тем, что его потревожили.  - Qu'est-ce-que vous voulez.

- Эдди! - крикнул.  - Хватит валять дурака. Какой-то тип разыскивал Меган. Человек не выпускал его из рук. - Да хватит тебе, Эдди! - Но, посмотрев в зеркало, он убедился, что это вовсе не его закадычный дружок. Лицо в шрамах и следах оспы.

Как я могла не выключить монитор. Сьюзан понимала: как только Хейл заподозрит, что она искала что-то в его компьютере, то сразу же поймет, что подлинное лицо Северной Дакоты раскрыто. И пойдет на все, лишь бы эта информация не вышла из стен Третьего узла. А что, подумала Сьюзан, если броситься мимо него и побежать к двери. Но осуществить это намерение ей не пришлось. Внезапно кто-то начал колотить кулаком по стеклянной стене.

Она постучала пальцем по кипе документов: - Вот твоя жизнь, Чед Бринкерхофф.  - Но, посмотрев на него, смягчилась.
