5 Basic Components of Electronics and Their Functions

When we study electronics, the first thing we have to do is learn and recognize the basic components of electronics. That way, we will more easily learn electronics and build an electronic system that can be implemented in everyday life. The following are 5 types of basic electronic components and their functions and symbols that you should know, consisting of resistors, capacitors, inductors, diodes, and transformers.

  1. Resistor
    Resistors if translated means prisoners or obstacles, which function to inhibit the current flowing in a closed circuit. The ability of resistors to inhibit our current is called resistance which is expressed in units of Ohm (Ω). The magnitude of the resistance value of a resistor can be seen from the color bands found on the resistor body.

  2. Capacitors
    Capacitors are one of the 5 basic components of electronics whose function is important for you to know because they are often used. Capacitors or also called condensers are components that are capable of storing and releasing electrical charges.
    The unit of the capacitor is called Farad, which shows the ability of the capacitor to store an electric charge or capacitance. Farad was taken from the name Michael Faraday, a scientist who invented the capacitor.
  3. Inductor
    Inductors are components that are used as inductive loads. The inductor serves as an energy storage in the magnetic field due to the electrical voltage through it. The ideal inductor consists of wire wrapped around without a resistance value. The electrical properties of an inductor are determined by the length of the inductor, the diameter of the inductor, the number of turns, and the material surrounding it. The inductance of an inductor is expressed in Henry units.
  4. Diodes
    Diodes are electronic components that function to deliver electric current to one direction and inhibit electric current from the opposite direction. Diodes can also be used to control currents, namely as electronic switches. Diodes consist of 2 electrode components namely Anode and Cathode.
  5. Transistor
    The transistor is a basic component of electronics that you should know because it has many functions and is a component that plays a very important role in this modern electronic world. In principle, the transistor consists of two diodes which are joined together. The transistor consists of 3 legs namely Base (B), Collector (C), and Emitter (E). So that the transistor can work, the legs must be given a voltage, this voltage is called bias voltage. Base-Emitter is given forward voltage, while Base-Collector is given reverse voltage. The nature of the transistor is that between the Collector and Emitor there will be a current (the transistor will deliver) if there is a base current. The greater the base current the greater the delivery.
    Some transistor functions include as a current amplifier, as a switch, voltage stabilization, signal modulation, rectifier and so on.

How to Take Care of Electronic Goods To Stay Good

Electronic goods seem to have become a part of our lives, almost all the items that fill the house are good electronic goods that are useful to alleviate human work as well as entertainment. We realize that this item requires maintenance so that its lifetime is more than the factory that produces it. Care is taken to keep the machine healthy and clean. But there are rarely people who care to care for electronic goods they have. Feeling lazy or do not know what to do to care for these tools. Here we submit an easy way to treat it:


• Store electronic items with wrappers so they are not exposed to dust. Besides that, it also avoids direct impact. Do not forget the container must also have a hole so that heat from electronic goods can come out.
• Clean electronic items using a cloth from a soft material such as a cloth to wipe both the screen and other parts.
• If there is a sticky stain, use a special cleaning liquid/lens cleaner to clean the stains that stick.
• Do not use electronic items too long without a pause to remove heat after being used for a long time.
• Store electronic items in a room that is cool enough but not damp because moisture can accelerate damage to electronic goods.
• Avoid direct sun contact and hot rooms. Excessive heat can damage existing components. An example of a hot room is a car parked in the sun.
• If you do not understand how to repair electronic items, take them to a service area that is truly trustworthy, or a product service center.
• Save your electronic warranty card. Generally, you get a free service opportunity or product maintenance. This is a thrifty way to still be able to use your electronics.
• Do not allow electronic goods to remain on when they are finished, turn them off immediately.
• Keep electronic items away from children and food and drinks. Who knows when food or drinks can contaminate and even damage your electronics.


Maintenance of electronic goods not only makes the life of the item long, on the other hand, but there are also many advantages that we get as the owner.


• Items that should have been damaged. Regular maintenance takes longer and avoids these items from damage that requires us to pay technicians. Very saving isn’t it?
• Maintenance prevents us from buying new items because old items have been damaged.
• Does not make us bother to adjust to different ways of using.
• Maintenance of electronic goods has accustomed us to become personally responsible for the items we have.
• Make us like people, without us knowing other people also imitate us to do the same thing as we do.
We should get used to being responsible for taking care of the things we have. Because it is important to note that the use of electronic goods that are too often is … Read More

When you discover the antivirus program within the listing, find the uninstall choice, which must be in the identical folder. The College of Tartu has bought a Symantec Antivirus license for all its computer systems. Until you determine to improve, you’ll solely get handbook scan capabilities, and no actual-time protection.

Microsoft Security Necessities for Home windows 7, and Windows Defender for subsequent variations, provide constructed-in safety towards malware. In these conditions, you have to obtain an uninstaller program from the antivirus scanner company to take away all information associated with the antivirus.

Sophos Dwelling not only supplies superior safety towards ransomware, it will probably detect a ransomware attack in progress, block it, and routinely roll back your recordsdata to an unencrypted state. A whitelist-primarily based safety system only allows known good packages to run.

In some situations, a legitimate antivirus program cannot uninstall as a result of it or the software used to uninstall it’s corrupt, dangerous, or lacking. It is very important stick only with antiviruses which have a positive status. Working (the actual-time safety of) multiple antivirus packages concurrently can degrade performance and create conflicts.
