Electronic components form parts of electronic circuitry, and are used or manufactured in the field of electronics, which is the study of electrical devices used for controlling electrically charged particles or the flow of electrons to execute any electrical operation. Some of the most common electronic components are as follows: Resistor: A resistor resists electric current, and the resistance is measured in ohms. Colors on the body of the resistor are a code for the value. Different colors represent the numbers from 0 to 9. In a variable resistor, resistance can be varied by moving a knob or slider. A variable resistor is used to control volume in many devices. Capacitor: This is measured in farads. A capacitor is used for storing electrical charges that can be released upon demand. Capacitors can be of different types - electrolyte and ceramic disc are two of them. Diode: A semiconductor device, diodes allow current to flow in one direction only. Small, cheap and lasting, ligh...

In the present environment when technology is progressing at a tremendous pace, obsolescence and redundancy are common phenomena leading to surplus inventory. Several cities have excellent surplus electronics stores, and once you find one, you are in for a pleasant surprise. The above factors have made it difficult for manufacturers to make new components for earlier generations of products. Although the purchase of new components has several advantages like long life expectancy and proper maintenance service, they are more expensive and subject to more failure rates during the break-in period. You should consider the following factors while buying surplus or used components: reliability, useful life, vendor, warranty or test capability, selection support and price. You can now find more vendors to choose from when purchasing surplus components. This is partly because of the expanding pool of used equipment left over after modernizations, and through new technology such as the Int...

For most of us our day starts with a ring tone of an electric alarm clock. Then as we get ready in the morning we use a couple of other devices ranging from an electric shaver to an electric iron. The point here is that we have hardly started our day and most of our morning is spent using various electronic devices and components. The list of electronic products that we use in a week would be so long that most of us would be shocked on seeing the amount of dependence on these products. As you must have realized by now, these Electronic products and components form a major part of our daily life. They either provide us a useful function or they entertain us. Irrespective of the purpose they perform, we all would agree that we can't survive without these products. These electronic components have become a major part of our daily life, whether we think so or not. Our dependence on these electronic gizmos is only increasing everyday. Nobody needs to be a technology expert to reali...

It is hard for the current generations of people to think about entertainment without the assistance of electronic components. Virtually even type of home entertainment in use today relies on electronics at some point either in its manufacture or in its operation. Television, radio, CD and DVD players, even electronic keyboards and video games all rely on parts that are roughly defined as electronic. The definition of electronics is accepted to be the study of the flow of electrons through various materials and conductors. Electronics are also the equipment or products that use electron flow in order to operate. Examples of electronics equipment include amplifiers, oscillators or radio receivers. While electronics were used in the late 19th century in such devices as telephones and telegraphs, it was not until the invention of the radio that electronics took a giant leap forward both in understanding and in applications. Of course, ever since its invention, the radio has been u...

Basic Components and Supplies to Start Out Working on electronic projects is a great way of learning electronics and depending upon the project undertaken, a number of tools and electronic components may be needed accordingly. There are some basic electronic components and supplies which are needed in almost all electronic projects and are a 'must have.' The first electronic components that you need to look into are resistors. You should have a good range of resistors in different values ranging from one ohm to 10 mega ohms with a 5% tolerance. Carbon film resistors are a good choice for small electronic projects. They are inexpensive and readily available from both online and offline merchants. Another important component that is needed are capacitors. Ceramic disc capacitors or electrolytic capacitors are both good choices for beginning electronics projects, and again, a good variety would be needed in terms of values. Lower voltage capacitors (up to 50V) would certainly...

To be able to test electronic components accurately is essential to identifying faults for any electronic repairer. Top quality electronic testing equipment is therefore much sought after. If you are involved in electronic repairs, professionally or just as a hobby, you will know just how much time good equipment saves you. Normally, however, this type of equipment to test electronic components can be relatively expensive, especially for do it yourself enthusiasts and people thinking about starting a small or part-time business. What many people are unaware of is just how easy it is to make your own gear and multimeter to test electronic components to the standards of top of the range brands, but at a fraction of the cost. All you need is the necessary know-how. There are some guides available to show beginners how to test electronic components and how to repair electronic devices and appliances. You should be looking for the following things when evaluating such a guide. Good ele...
