Basics of Breadboard

The electrical breadboard is a prototyping board on which electronic components are connected for testing.
A breadboard is a perforated block of plastic which has block clips under the plastic. The clips are also known as the contact points. The spacing between each point is 0.1 mm. Most breadboard models have 56 clips.

Internally these clips are linked together. The most commonly used model of the breadboard is shown below:

Resistors, capacitors, inductors, and other components are simply inserted in these clips.

How to make a simple circuit?

Consider the circuit below.

The battery connects in series with the resistor via two wires.

Let's implement this circuit on the breadboard.

The left leg of resistor connects to a clip in the purple block (mentioned before). The vertical clips in this section are internally linked together. So adding black wire to any of vertical clips will join them in series.

Similarly, the live terminal (+ve terminal) of battery connects to the right limb of the resistor.
