• Simple Series Circuit Meaning For Kids

Whenever you have circuits that consist of more than one electronic component, those electronic components must be linked together. The two ways to connect components in a circuit are in series and in parallel. In a series connection, components are connected end to end, so that current flows first through one, then through the other. Creating a Simple Circuit This is the simplest complete circuit in this collection of experiments: a battery and an incandescent lamp. Connect the lamp to the battery as shown in the illustration, and the lamp should light, assuming the battery and lamp are both in good condition and they are matched to one another in terms of voltage.

Reading the Circuit Diagram

The circuit diagram (also known as a schematic diagram) is shown below:

This circuit diagram tells us (clockwise from the battery): Connect the positive terminal of the battery (red battery clip lead) to the 1 kilo-ohm resistor. Connect the other lead of the resistor to the anode of the LED. Connect the cathode of the LED to the negative terminal of the battery (black battery clip lead).

Often the battery or power source is not shown in the circuit diagram. It will be represented by text that will show what voltage must be connected across the circuit. This diagram shows the alternate circuit:

Building the Circuit

Get the parts and tools ready:

This video clip will show you what you will be doing – step by step instructions follow:

Step 1: Insert the LED into the Breadboard

Start by bending the longer lead of the LED as shown in the previous photo. Plug the longer lead (anode) of the LED into the top rail of the breadboard and the other lead into a hole in the main part of the breadboard as shown:

Step 2: Insert the Resistor into the Breadboard

Use the side cutters to remove a 1k resistor from the string of resistors if they are taped together. Cut the resistor lead as near to the tape as possible. Don't try to remove the tape as this will leave a sticky mess on the end of the resistor lead which will then end up in your breadboard.

Bend the leads of the resistor as shown below. Plug one of the resistor leads into a hole directly below the cathode lead of the LED and the other lead into a hole below the middle channel of the breadboard. This connects the LED cathode to one of the resistor leads. It does not matter which way around the resistor is plugged into the breadboard.

Step 3: Insert the Wire Link into the Breadboard

Insert a wire connector into a hole directly below the resistor lead and into the bottom rail of the breadboard.

Step 4: Insert the Battery Clip into the Breadboard

Plug the red (positive) wire of the battery clip into the top rail of the breadboard. Plug the black (negative) wire of the battery clip into the bottom rail of the breadboard.

Step 5: Plug the Battery into the Battery Clip

Finally plug the battery into the battery clip to power up the circuit and switch the LED on. Make sure to connect the battery clip to the battery the right way around. The opposite type of connector on the battery clip must be connected to the battery terminals, i.e. the battery and battery clip each have a pair of terminals and they will only connect to each other one way. If you try to connect them the wrong way, they won't clip together, but they will put reverse polarity on the circuit for a moment which may destroy the circuit, so be sure to connect the battery the right way around the first time.

How the Breadboard and Circuit Works

The red lines in photo below show how the breadboard is connected internally. The figure shows only some of the vertical connections, they repeat as shown.

The top and bottom parts of the breadboard are identical and have four horizontal connecting strips. The middle of the breadboard has vertical connecting strips separated by a horizontal channel in the middle.

Each individual red line or connecting strip is electrically isolated from every other strip.

Any component lead that is plugged into a hole or 'tie point' of the breadboard will be connected to whatever is plugged into a hole of the same connecting strip as marked in red in the photo.

This photo shows the circuit built in this tutorial with the connecting strips of the breadboard that are used by the circuit in blue.

The red lead from the battery is joined to the LED via the top horizontal strip of the breadboard. The LED connects to the resistor using a top vertical strip. The resistor is not shorted out because it jumps across the middle insulated channel of the breadboard to a vertical connecting strip below. The wire link connects the bottom resistor lead to the bottom horizontal connecting strip which is then connected to the black lead of the battery.

I hope that you enjoyed this tutorial and found it useful. This tutorial was kept simple as an introduction to some basic electronic components and so that you can learn how a breadboard works before tackling more complex circuits.

2. R1_100 ohms—Same with R2.
3. A variable DC power supply or 10V Fixed regulator.

Make simple series circuit

What are the characteristics of a series circuit?

How To Make A Simple Series Circuit

First of all, he builds the simple series circuit by using one resistor as Figure 1.

He installed all resistors into the breadboard. Then, apply the 10V power supply to the resistor-1K as a complete circuit.

The simplest electronic circuit

In the circuit diagram, the voltage drop across R1-1K is 10V. Because it is connected in parallel with the battery, 10V.

But how many current R1 is using?

Series circuit current flow

Then, he measures a current of the resistor-1K as Load of the circuit.
We will know current that flow in the resistor.

Measure the current that flows through the resistor

Next, he connects the 100 ohms resistor in under 1K resistor as below.

Measure voltage at the series form

He wants to know the voltage across each resistor.
So he uses the digital voltmeter measure voltage them.
The voltage across various resistor are different voltage, as follows.

• First, the voltage across R1-1K is 9.28V
• Second, the voltage across R2-2K is 0.933V
• And, the voltage across both resistors, R1+R2 are 9.28V and 0.933V = 10.17V
  OR or this source voltage.

Then he measures current at various places.
As Figure 4 series circuit diagram

The Current flows various resistors
R1 = 0.009A
R2 = 0.009A
R1+R2 = 0.009A
Thus, all parts have current equal 0.009A

Figure 5. He studies the series circuit by measuring voltage and current at various parts.

Important features of the series circuit.
1. Electric current flowing through the same and have the same direction throughout the entire circuit.
2. The total resistance of the circuit is equal to the sum of the individual resistances in the circuit together.
3. The voltage across various parts of the circuit. When taken then combined will equal the voltage at the source.
