What is an Electronic Circuit?
An electronic circuit is a conductive path for the passage of electricity or current. It is also known as an electric circuit. A conductive wire is use to establish the relationship between the voltage source and the load. An ON / OFF switch and fuse are also use between the source and the load.
When is a Circuit Call an Electronic Circuit?
A circuit remains composed of electronic components such as a capacitor, resistor, diode, transistor, inductor, coil, transformer, etc. It is called an electronic circuit. These components container remain either through-hole or CMS.
These components or devices are connected through conductive tracks (usually copper) or conductive cables through which electric current can flow. Simply put, these electronic components are solder onto a print circuit board to perform a predefined task.
A circuit called an “electronic circuit” instead of an “electric circuit” must have at least one active component.
What are Active Electronic Components?
Active electronic components are those that can control the flow of electricity. Most published circuit boards (PCBs) have at least one lively part.
Example: transistors, integrated circuits, reason gates, vacuum tubes, silicon-controlled rectifiers (SCR).
What are Passive Electronic Components?
Inactive components are those that have neither gain nor directivity. They are also call electrical elements or electrical components.
Example: resistors, capacitors, diodes, inductors.
Types of Electronic Circuits
A circuit can remain of the following types:
1. Analog Electronic Circuit
Analog electronic circuits are those in which signals can be endlessly modification over the period to match the information presented.
Example: Electronic devices such as power amplifiers, power amplifiers, tuning circuits, radios, and televisions are mostly analog.
2. Digital Circuit
A digital circuit is a circuit where the signal has one of two discrete levels: ON / OFF or 0/1 or true/false. Transistors are use to create logic gates that perform Boolean logic.
Example: multiplexers, demultiplexers, encoders, decoders, counters, flip-flops
3. Mixed-Signal Circuit
Mixed-signal circuits, also called hybrid circuits, comprise elements and properties of both analog and digital circuits.
Simple Electronic Circuits for Beginners
In general, the success of the first projects in electronics plays a decisive role in the careers of engineering students. Many students have given up on electronics because they failed the first try. After a few failures, the student maintains the mistaken assumption that projects that work today may not work tomorrow. We, therefore, endorse that beginners start with the following tasks, which will pay off the first time and motivate them for their work. Before continuing, you should understand how to operate and use a breadboard. This article presents the ten best basic electronic circuits for beginners and mini-projects for engineering students, not senior projects. The following circuits belong to the basic and minor categories.
DC Lighting Circuit
A DC power source is use for a small LED with two terminals, namely the anode and the cathode. The anode is + ve, and a cathode is -ve. A lamp with two connections, positive and negative, is use as a load. The + ve terminals of the lamp are connected to the anode pole of the battery, and the -ve pole of the battery is connect to the -ve rod of the storm. A switch is connect between the wires to provide DC voltage to the LED lamp.
Rain Alarm
The next rain turn is use to warn when it is going to rain. This circuit is used in households to protect their wash clothes and other items sensitive to rain when they are home most of the time to do their work. The components required to build this circuit remain probes. 10K and 330K resistors, BC548 and BC 558 transistors, 3V battery,
