An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products , available in a singular form and are not to be confused with electrical elements , which are conceptual abstractions representing idealized electronic components.
Basic Electronics Tutorial Pdf Figure 1 shows a circuit with five elements. Basic electronics is all about electrical components and the circuits consisting of those components. Here the bits O0 and O1 are considered as outputs while the bit V is use to validate the output.
Electronic Components, Parts and Their Function
Resistance is the property of opposing the flow of electrons, in a conductor or a semiconductor. A Resistor is an electronic component which has the property of resistance. Where V is Voltage and I is Current.
It would really be difficult to manufacture the resistors with each and every value. Hence, few values are chosen and the resistors of such values are only manufactured. In practice, the resistors with near values are chosen to match the required applications.
A process called color coding is used to determine the value of resistance for a resistor, just as shown in the above figure. A resistor is coated with four color bands where each color determines a particular value. The below table shows a list of values which each color indicates. The first two colored bands indicate the first and second digit of the value and the third color band represents the multiplier number of zeroes added.
The fourth color band indicates the tolerance value. Tolerance is the range of value up to which a resistor can withstand without getting destroyed. This is an important factor.
The following figure shows how the value of a resistor is determined by color code. In these five band resistors, the first three bands represent digits, fourth one indicates multiplier and the fifth represents tolerance. After having gone through different details regarding resistors, we have some terms to learn. Also we have to deal with different behaviors of a resistor for few types of connections. There are a few terms which we need to discuss before going into the type of resistors we have.
One needs to get introduced to these terms at this stage and can understand them as we progress further. Resistance is the property of a resistor that opposes the flow of current. When alternating current goes through a resistance, a voltage drop is produced that is in-phase with the current. The resistance offered to the alternating current because of the capacitances and inductances present in the circuit, can be understood as reactance.
Depending upon the phase i. Impedance is the effective resistance to alternating current arising from the combined effects of ohmic resistance and reactance. Basic Electronics - Resistors Advertisements. Previous Page. Next Page. Previous Page Print Page. Dashboard Logout.
BASIC ELECTRONIC COMPONENTS MODEL ECK-10 Instruction Manual
Electronic elements that make up a circuit are connected together by conductors to form a complete circuit. An active component is an electronic component which supplies energy to a circuit. A voltage source is an example of an active component in a circuit. When current leaves from the positive terminal of the voltage source, energy is being supplied to the circuit. As per the definition of an active element, a battery can also be considered as an active element, as it continuously delivers energy to the circuit during discharging. A current source is also considered an active component. The current supplied to the circuit by an ideal current source is independent of circuit voltage.
If you are interested in learning everything about electricity, you should start by understanding the basic components that make up any electrical design and how they work. Think about how the great pyramids of Egypt were built using just blocks of rock. The rocks themselves were nothing, but when combined with a careful design they formed such grand structures! Similarly, you need to know about the basic electrical components and how they work together to create wonderful modern electrical systems. Below you will find information about the most common electrical components:. The very first component that you should know about is the resistor. It is fairly easy to assume that a resistor, as the name suggests, will resist electricity that flows through it, and you would be correct in that assumption too!
Passive Components: Components like resistance, capacitance RESISTANCES: Resistors can be made to control the flow of current, to work INDUCTORS: Like capacitors, inductors also store energy in one part of AC.
how to test electronic components on a circuit board pdf
These Electronic components are basic electronic parts packaged in a discrete form with two or more connecting leads or metallic pads. Electronic Components are intended to be connected together, usually by soldering to a Printed Circuit Board PCB , to create an electronic circuit with a particular function for example an amplifier, radio receiver, oscillator, wireless. Passive Electronic Components are those that do not have gain or directionality. They are also called Electrical elements or electrical components. Resistors, Capacitors, Diodes, Inductors.

This can be a challenging task, because different components call for different test procedures. Mobile circuit boards are generally more comfortable to use than television boards. Wires connected at 'crossroads' should be staggered slightly to form two tin whiskers on printed circuit boards consequences for. A multimeter that can check resistance can also be helpful, providing the resistor is already removed from the board measuring it while still soldered in can give inaccurate results, due to connections with the rest of the circuit. The circuit board itself is a thin plastic rectangle, usually mounted inside the equipment case.
Resistance is the property of opposing the flow of electrons, in a conductor or a semiconductor. A Resistor is an electronic component which has the property of resistance. Where V is Voltage and I is Current. It would really be difficult to manufacture the resistors with each and every value.
Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are also used in automobiles, kitchen appliances, medical equipment and industrial controls. At the heart of these devices are active components, or components of the circuit that electronically control electron flow, like semiconductors. However, these devices could not function without much simpler, passive components that predate semiconductors by many decades. Unlike active components, passive components, such as resistors, capacitors and inductors, can't control the electron flow with electronic signals.
Electronic Components and Their Function
There are numerous basic electronic components that are used for building electronic circuits. These components include resistors, diodes, capacitors, integrated circuits, and so on. Some of these components consist of two or more terminals that are soldered to circuit boards. Some may be packaged types like integrated circuits in which different semiconductor devices are integrated. Here is a brief overview of each of these basic electronic components and you can get in-depth information by clicking links attached to each component.
Мидж… - Джабба попробовал извиниться. - Позволь мне объяснить. - Голос его, однако, мягче не. - Во-первых, у нас есть фильтр, именуемый Сквозь строй, - он не пропустит ни один вирус. Во-вторых, если вырубилось электричество, то это проблема электрооборудования, а не компьютерных программ: вирусы не отключают питание, они охотятся за программами и информацией.
Сьюзан кричала и молотила руками в тщетной попытке высвободиться, а он все тащил ее, и пряжка его брючного ремня больно вдавливалась ей в спину. Хейл был необычайно силен. Когда он проволок ее по ковру, с ее ног соскочили туфли. Затем он одним движением швырнул ее на пол возле своего терминала. Сьюзан упала на спину, юбка ее задралась. Верхняя пуговица блузки расстегнулась, и в синеватом свете экрана было видно, как тяжело вздымается ее грудь. Она в ужасе смотрела, как он придавливает ее к полу, стараясь разобрать выражение его глаз.
