# Series Circuits Study Guide

INTRODUCTION

An electric circuit mainly includes the arrangement of elements for energy transmission, conversion, and storage. In the series circuit, the energy enters through one source and leaves out through another sink. Throughout the circuit, various resistance is linked end to end. This form of connection is also known as **cascade connection**, where the flow of current is through only one direction.

## SERIES CIRCUITS OVERVIEW

- In the series circuit, the same magnitude of current passes from one path, and this current travels all across the resistance.
- The meaning of a series circuit says that the negative terminal of the component is joined with the positive terminal connected in series.
- Moreover, in the series circuit, the current passes at an equal magnitude and all the components are arranged in a line.

The **advantages of the series circuit** are:

- The current in the circuit remains constant.
- The circuit does not heat up speedily and thus will not catch fire easily.

## SERIES CIRCUIT DEFINITION

- The series circuit definition states that a series circuit is a path where the current flows from one component to another through a single path.
- In these types of series circuits, the negative terminal of the component is connected with the positive terminal and vice versa.
- The
**disadvantages of a series circuit**: since there is only a single path for the flow of current, if the circuit breaks, the appliance will be cut out of the current.

## DIAGRAM OF SERIES CIRCUIT

The series circuit diagram is usually designed as:

## Examples Of Series Circuits

The series circuit examples are as follows:

- Water heater
- Freezers
- Refrigerators
- Lamps
- Bulb
- Well water pump
- Flashlights

Moreover, there are various other applications of series circuits in our daily life.

## SERIES CIRCUIT FORMULA

The series circuit formula is:

**Total Resistance = R1+R2+R3……so on**

## SUMMARY

- A simple series circuit is designed with one load resistance and only one battery, in which the negative terminal of the component is joined with the positive terminal of the series combination.
- In the series circuit, the current passes at an equal magnitude.
- The formula of the series circuit is Total Resistance = R1+R2+R3……so on

## FAQs

**1. What is a simple series circuit?**

A simple series circuit is designed with one load resistance and only one battery, in which the negative terminal of the component is joined with the positive terminal of the series combination.

**2. How does a series circuit work?**

In the series circuit, the total resistance is always equal to the sum of all the resistances, keeping the voltage difference in the resistors and the sum of the dropped voltages all across the component of the circuit. Any break or fault in the circuit stops the flow of current.

**3. What are 2 examples of a series circuit?**

- Water heater
- Freezers

**4. Why is the series arrangement not used for the domestic circuit?**

Because in the series circuit, the voltage is divided into small voltages to decrease the flow of current. Due to this, the device gets too hot and ceases to work perfectly.

**5. What are the three rules of a series circuit?**

- Total Resistance = R1+R2+R3……so on.
- The current is the same throughout. And the voltage is divided by equal resistance.
- The sum of each voltage drop is equal to the voltage of the battery.
