A semiconductor is an electronic component that conducts an electricity under some specific conditions, it is the best medium to control an electrical current. Semiconductors have been manufactured purposely as single discrete devices and as integrated circuits. Its conductance varies depending on the current or voltage applied to a control electrode, or on the intensity […]

Electronic Circuits

An electronic circuit is created with a combination of individual electronic components like resistors, transistors, capacitors, inductors, and diodes, connected by conductive wires or traces through which electric current can flow. The combination of the electronic components and wires allows various simple and complex operations to be performed, the electronic circuits can amplify the signals, […]

Consumer Electronics

Technology is being bought by people no matter how expensive it is to make life easier. Most of the electronics today are portable, wearable, and even connected to the social world. The electronic industry has employed a large number of engineers, designers, marketers, salespeople, customer service representatives, and finance experts to continuously improve the products […]

Electronic Devices

Electronic devices are utilized for controlling the flow of electrical currents for the purpose of information processing and system control. Electronic materials are the type of materials which are typically used as core elements in a variety of device applications. Electronic devices are generally small devices and can be grouped together into packages called integrated […]


Resistor is a universal component in an electronic equipment. It is a critical electronic component in every circuit. Resistor is a passive two-terminal electrical component that applies electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, and establish predetermined voltages or currents […]

Light-Emitting Diode

Light-emitting diode, or more commonly known as LED is a two-lead semiconductor light source. It has a p-n junction diode that when activated, it emits light. Not like lasers, the color of the light emitted from a LED is neither coherent nor monochromatic. However, it has a narrow spectrum with respect to the human vision, […]

Electronics: An Introduction

Electronics is the science that controls the electrical energy, wherein the electrons have a fundamental role. Electronics deals with the electrical circuits that involve active electrical components that are associated with passive elements like circuits. The science of electronics is considered to be a branch of physics and electrical engineering. It has been the greatest […]

Microelectronics: An Introduction

What is microelectronics? By definition, microelectronics is a specialized field that is under the discipline of Electronics Engineering. In electronics, it deals with tiny, or microscopic components to manufacture electronics. It has been rapidly evolving, as the demand for small and less costly devices advances, microelectronics continues to expand. There are three main areas microelectronics […]


A battery is the source of an electrical energy that is provided by one or more electrochemical cells after it is converted from the stored chemical energy. Batteries are subdivided into two categories, the primary batteries, and the secondary batteries. Primary Battery It is the most commonly used battery for portable devices that have a […]

Electronics Safety

Although electronics deal with low voltage devices, it still has the potential to put yourself into harm. Devices or circuits that use 120 VAC power from an electrical outlet can put you into an imminent danger and potentially kill you. It is best to take the precautionary measures and safety guidelines to keep yourself safe […]
