Electronics are the lifeblood of our daily lives, it engulfs us in this technological universe. We know how to use these machines because they are constantly used by us in our daily lives, be it a smartphone or one of the kitchen appliances. Wondering how all those gadgets actually work? To know what a resistor is, along with other basic electronic components. If you are into do-it-yourself (DIY) electronics, learning about those components and how they work is a must.
Resistors - Resistors are small, static components that control the flow of electrical current in a circuit. They are precisely built to restrict the current and lower in voltage. There are different kinds of resistors available in the market, like fixed which have a set resistance and variable whose value can be changed.
Capacitors: Components which store electrical energy in an electric field. Voltage regulators are used to prevent damage due from output voltage spikes or unwanted noise, and for storing energy in timing circuits.
Diodes: The semiconductor components that only allow the current to flow in a single direction. They are most commonly used in rectifier circuits that provide a means for converting AC voltage into DC output.
Bye transistors - electronic switches that are keys to amplifying and switching one electric signal over another which is crucial for all kind of computer functions. They are available in two varieties: NPN and PNP.
LED: Light-Emitting Diode; These are diodes that radiate light when a circuit is turned on. LEDs are common in commercial and residential lighting, they the modern light source available today for a variety of applications.
Although electronics might seem complicated, they all are based on basic principles. Well, one of those is Ohm's Law that explains the relationship between current, voltage and resistance. This definition says that, the amount of current which a conductor connecting those two points could carry is directly proportional to difference in voltage between these 2 points and inversely proportional to its impedance (resistance).
A related but important concept are that of circuit elements - resistors, capacitors and inductors which come into play while making an electronic circuits. These properties control the action of these elements, which include resistance, capacitance and inductance.
Electronic circuits are composed of various components which include passive components like resistors, capacitors and inductors as well as active elements such as transistors... integrated circuits. Resistors and capacitors are examples of passive components as they require no energy supply in order for them to work, yet the power from an external system can be used to achieve this. Active components, which rely on a source of energy and not only directional but have the ability to further control signal power are needed as well,. Transistors (bipolar junction -BJTs BJT or FETs) represent this type of controllable activd directionality.
ICs (Integrated circuits - Chips that embed a variety of electronic component) They are a key in the design of complex circuit such as microprocessors, memory chips.
There is enough content out there for people new to the world of electronics. But then that would be like learning from online tutorials / courses to get the basic idea of circutry and components.
Real beginners tips like select the right components for your project, use bread board to simulate Circuits and learn how read circuit diagrams...the usual stuff. It also helps to have a general knowledge of electronics too, including Ohm's Law and components used in circuits.
Given this, we can conclude that they are the first thing many modern electronics circuits have in common. It is the knowledge of how they work and operate that, for those who pursue DIY electronics, cannot be passed by. Anyone willing to learn can start making electronic circuits and devices with a few simple tools.
