How Electronic Components WorkVIDEO ON THE TOPIC: The Top 7 Best Acoustic Guitar Amplifiers For Performers - 2019
Electronic gadgets have become an integral part of our lives. They have made our lives more comfortable and convenient. From aviation to medical and healthcare industries, electronic gadgets have a wide range of applications in the modern world.
In fact, the electronics revolution and the computer revolution go hand in hand. Most gadgets have tiny electronic circuits that can control machines and process information. Simply put, electronic circuits are the lifelines of various electrical appliances. This guide explains in detail about common electronic components used in electronic circuits and how they work. In this article I will provide an overview on electronic circuits.
Then I will provide more information on 7 different types of components. An electronic circuit is a structure that directs and controls electric current to perform various functions including signal amplification, computation, and data transfer. It comprises several different components such as resistors, transistors, capacitors, inductors, and diodes. Conductive wires or traces are used to connect the components to each other.
However, a circuit is complete only if it starts and ends at the same point, forming a loop. The complexity and the number of components in an electronic circuit may change depending on its application. However, the simplest circuit consists of three elements, including a conducting path, a voltage source, and a load.
The electric current flows through the conducting path. Though copper wires are used in simple circuits, they are rapidly being replaced by conductive traces. Conductive traces are nothing but copper sheets laminated onto a non-conductive substrate. The primary function of a circuit is to allow electric current to pass through it safely. So, the first key element is the voltage source. It is a two-terminal device such as a battery, generators or power systems that provide a potential difference voltage between two points in the circuit so that current can flow through it.
A load is an element in the circuit that consumes power to perform a particular function. A light bulb is the simplest load. Complex circuits, however, have different loads such as resistors, capacitors, transistors, and transistors.
As mentioned before, a circuit must always form a loop to allow the current to flow through it. In other words, any circuit that does not form a loop is an open circuit. A closed circuit is one that forms a loop without any interruptions. Thus, it is the exact opposite of an open circuit. For example, a circuit connected to a dead battery may not perform any work, but it is still a closed circuit.
In the case of short-circuit, a low-resistance connection forms between two points in an electric circuit. As a result, the current tends to flow through this newly formed connection rather than along the intended path. However, short circuits usually lead to serious accidents as the current can flow at dangerously high levels.
Hence, a short circuit can damage electronic equipment, cause batteries to explode, and even start a fire in commercial and residential buildings. Most electronic appliances require complex electronic circuits. It comprises a plastic board with connecting copper tracks on one side and lots of holes to affix the components.
When the layout of a circuit board is printed chemically onto a plastic board, it is called a printed circuit board or PCB. Though PCBs can offer a lot of advantages, most modern instruments such as computers and mobiles require complex circuits, having thousands and even millions of components. They are the tiny electronic circuits that can fit inside a small silicon chip. Jack Kilby invented the first integrated circuit in at Texas Instruments. The sole purpose of ICs is to increase the efficiency of the electronic devices, while reducing their size and manufacturing cost.
Over the years, integrated circuits have become increasingly sophisticated as technology continues to evolve. Thanks to modern technology, electronic circuit building process has been completely automated, especially for building ICs and PCBs. The number and arrangement of components in a circuit may vary depending on its complexity.
However, it is built using a small number of standard components. The following components are used to construct electronic circuits. Capacitors are widely used to build different types of electronic circuits. A capacitor is a passive two-terminal electrical component that can store energy in an electric field electrostatically. In simple terms, it works as a small rechargeable battery that stores electricity. However, unlike a battery, it can charge and discharge in the split of a second.
Capacitors come in all shapes and sizes, but they usually have the same primary components. There are two electrical conductors or plates separated by a dielectric or insulator stacked between them. Plates are composed of conducting material such as thin films of metal or aluminum foil.
A dielectric, on the other hand, is a non-conducting material such as glass, ceramic, plastic film, air, paper, or mica. You can insert the two electrical connections protruding from the plates to fix the capacitor in a circuit. When you apply a voltage over the two plates or connect them to a source, an electric field develops across the insulator, causing one plate to accumulate positive charge while negative charge gets collected on the other. The capacitor continues to hold its charge even if you disconnect it from the source.
The moment you connect it to a load, the stored energy will flow from the capacitor to the load. Capacitance is the amount of energy stored in a capacitor. The higher the capacitance, the more energy it can store. You can increase the capacitance by moving the plates closer to each other or increasing their size. Alternatively, you can also enhance the insulation qualities to increase the capacitance. Though capacitors look like batteries, they can perform different types of functions in a circuit such as blocking direct current while allowing alternating current to pass or smooth the output from a power supply.
They are also used in electric power transmission systems to stabilize voltage and power flow. It can supply the microcontroller with the necessary power for a split second to avoid a restart. In other words, it filters out the noise on the power line and stabilizes the power supply.
Unlike a battery, a capacitor releases its charge rapidly. Your camera batteries charge the capacitor attached to the flash gun. When you take a flash photograph, the capacitor releases its charge in a split second to generate a flash of light. In a resonant or time-dependent circuit, capacitors are used along with a resistor or inductor as a timing element. The time required to charge and discharge a capacitor determines the operation of the circuit.
A resistor is a passive two-terminal electrical device that resists the flow of current. It is probably the simplest element in an electronic circuit. It is also one of the most common components as resistance is an inherent element of nearly all electronic circuits. They are usually color-coded. A resistor is not a fancy device at all because resistance is a natural property possessed by almost all conductors.
So, a capacitor consists of a copper wire wrapped around an insulating material such as a ceramic rod. The number of turns and the thinness of copper wire are directly proportional to the resistance. The higher the number of turns and thinner the wire, the higher the resistance. You can also find resistors made of a spiral pattern of a carbon film.
Hence, the name carbon film resistors. They are designed for lower-power circuits because carbon film resistors are not as precise as their wire-wound counterparts. However, they are cheaper than wired resistors.
Wire terminals are attached to the both ends. As resistors are blind to the polarity in a circuit, the current can flow through in either direction. So, there is no need to worry about attaching them in a forward or a backward direction. A resistor may not look like much. However, it performs a vital function: controlling the voltage and the current in your circuit. In other words, resistors give you control over the design of your circuit.
When electric current starts flowing through a wire, all the electrons start moving in the same direction. Less amount of water will flow through a thin pipe because there is less room for its movement.
Similarly, when the current passes through a thin wire in a resistor, it becomes progressively harder for the electrons to wiggle through it.
In short, the number of electrons flowing through a resistor goes down as the length and thinness of the wire increases. Resistors have plenty of applications, but the three most common ones are managing current flow, dividing voltage, and resistor-capacitor networks. It can overheat other components and possibly damage them.
For example, if you connect an LED directly to a battery, it would still work. However, after some time the LED will heat up like a fireball. It will eventually burn as LEDs are less tolerant to heat.
But, if you introduce a resistor in the circuit, it will reduce the flow of current to an optimal level. Thus, you can keep the LED on longer without overheating it.
Woodbank does not monitor or record these emails. For many years the motor controller was a box which provided the motor speed control and enabled the motor to adapt to variations in the load. Designs were often lossy or they provided only crude increments in the parameters controlled. Modern controllers may incorporate both power electronics and microprocessors enabling the control box to take on many more tasks and to carry them out with greater precision. These tasks include:. In an open loop control system the controlling parameters are fixed or set by an operator and the system finds its own equilibrium state.

Power electronics is the engineering study of converting electrical power from one form to another. A lot of energy is wasted during this power conversion process due to low power conversion efficiency. It is estimated that the power wasted in desktop PCs sold in one year is equivalent to seventeen MW power plants! It is therefore very important to improve the efficiency of these power conversion systems. Research Showcase. Researchers at North Carolina State University have created a high voltage and high frequency silicon carbide SiC power switch that could cost much less than similarly rated SiC power switches. The findings could lead to early applications in the power industry, especially in power converters like medium voltage drives, solid state transformers and high voltage transmissions and circuit breakers.

The practical benefit of active devices is their amplifying ability. Whether the device in question be voltage-controlled or current-controlled, the amount of power required of the controlling signal is typically far less than the amount of power available in the controlled current. Because of this disparity between controlling and controlled powers, active devices may be employed to govern a large amount of power controlled by the application of a small amount of power controlling. This behavior is known as amplification.

Powering The World’s Critical Systems
An analog-to-digital converter ADC performs the reverse function. There are several DAC architectures ; the suitability of a DAC for a particular application is determined by figures of merit including: resolution , maximum sampling frequency and others. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals which connect to the screen drivers to display monochrome or color images.
