Electronic Circuits Course And Certification
What Is Electronic Circuit?
Electronic Circuit is the electric current that is made up of conducting components such as the capacitors, diode, resistors, inductors, coil, transformers, etc. These components or devices are linked to each other through conductive traces generally made up of copper or conductive wires by which electric current can pass through. In a more practical view, these electronic components are soldered together unto a Printed Circuit Board PCB board to perform its predetermined function.
Electric Current is a flow of electric charge in a circuit. The points where those electrons enter in an electrical circuit is known as the "source" of electrons. The point where the electrons leave in an electrical circuit is known as the "earth ground" or "return".
The Exit Point of the electric current in the circuit is called "return" because the electrons always end up in the source when they have successfully completed the parts of an Electrical Circuit.
Most Electronic Circuits are designed with the aid of Computer-Aided Design programs, or CAD. Most of the circuits you can see in digital computers are extremely complex and have millions of transistors in them, so CADs are the only more practical way to design them. The circuit designer would start out with a general specification of the functions of the circuit, then the Cad programs would lay out the complex patterns with all its interconnections.
Features And Components Of Electronic Circuits
Below are some of the Features Of Electronic Circuits.
1. Capacitors: Capacitors are the components of electronic circuits that can store electric charges temporarily. they come in different varieties with the most common ones being electrolytic and ceramic disk. they are made up of one or more pairs of conductors separated by an insulator.
2. Diodes: Diodes allow electric current to pass through them in one direction only. each diode in an electronic circuit has two terminals known as the anode and cathode. When the anode is charged, with positive voltage and the cathode is charged with a negative voltage, the electric current can then flow through. Reversing this voltage would prevent the current from flowing through.
3. Integrated Circuits (IC): An integrated circuit is a special device that has basically all the components that are needed in an electronic circuit. this component has diodes, transistors, and all other devices which are squeezed into a tiny piece of silicon. these components are used in a lot of electronic devices including computers, calculators, and watches.
4. Inductors: Inductors are passive components that store electrical energy in the form of a magnetic field. An inductor is simply made up of a coil of wire that is wound across some kind of core. This core could be a magnet or air. when the current is being passed through the conductor, a magnetic field is created around it. the magnetic field is stronger if the core is made up of the magnet.
5. Microcontrollers: Microcontrollers are very small computers that are used to control a multitude of devices, such as power tools, remote controls, medical equipment, and office machines.
6. Transformers: Transformers in an Electronic circuit is built using two coils of wires called primary and secondary coil, transformers are commonly used to step up or step down power.
7. Batteries: Batteries convert chemical energy to electrical energy. They act as both primary power and backup power of Electonic Circuits. The two different cells of a battery are the anode (+) and cathode (-).
8. Fuses: Fuses help to prevent components in the circuit from overloading with excessive current by breaking when there is excess current thus preventing the current from entering the circuit. A fuse is made up of connection body, support, contacts, and metal-fuse material such as zinc or copper.
Benefits Of Electronic Circuits
Below are some of the benefits of Electronic Circuits.
1. Electronic Circuits are easy to design.
2. Electronic Circuits makes it possible to eliminate error in a circuit because you design it with computerized tools.
3. The voltage at any point on an Electronic Circuit can be either high or low; hence there is a lesser chance of confusion.
4. It is more secure and reliable.
5. Electronic Circuits has higher accuracy
