The Light Emitting Diode (LED) is one of the most widely used electronic components today, found in everything from indicator lights to full-scale lighting systems. It is a type of diode that converts electrical energy into light energy, offering a highly efficient alternative to traditional bulbs. Unlike incandescent lamps that rely on heating a filament, […]
A Solid-State Relay (SSR) is an electronic switching device that performs the same function as an electromechanical relay (EMR) but without any moving parts. Instead of mechanical contacts, it uses semiconductor devices such as thyristors, Triacs, MOSFETs, or transistors to switch electrical loads ON or OFF. Because there are no moving parts, SSRs offer longer […]
A laser diode is a semiconductor device that emits coherent light through the process of stimulated emission. It operates similarly to a light-emitting diode (LED) but produces a focused, monochromatic, and coherent beam of light. The emitted light waves have the same wavelength, frequency, and phase. The laser diode was invented by Theodore H. Maiman, […]
A carbon film resistor is one of the most widely used fixed resistors in electronic circuits. It belongs to the carbon-based resistor family, where resistance is obtained from a thin layer of carbon deposited on an insulating substrate. Due to its moderate cost, good stability, reasonable accuracy, and wide resistance range, the carbon film resistor […]
Learn about digital logic families, their classifications, key characteristics, and how they differ in speed, power consumption, and practical applications in digital electronics. Digital electronic systems operate using binary logic levels, commonly represented as logic ‘0’ and logic ‘1’. The circuits that process these logic levels are built using logic gates, and these gates are […]
A power diode is a semiconductor device specifically engineered to conduct large currents and withstand high reverse voltages in power electronic circuits. It is fundamentally a PN junction diode, but its internal structure, doping profile, and packaging are optimized for high-power operation rather than low-level signal processing. In power electronic systems, power diodes play a […]
In this project, we will make a CD4047 Inverter Circuit, and we will also discuss why this type of inverter is not a good or reliable solution for real-world applications. An inverter is an electronic device that converts DC voltage into AC voltage. Inverters play a very important role in power backup systems, especially in […]
Artificial Intelligence in Electronics improves quality, inspection, and yield as components shrink and manufacturing complexity increases. Electrical components are becoming smaller and denser, making them harder to manufacture consistently. Fine-pitch BGAs, advanced packaging, high-speed connectors, miniaturized sensors and power electronics all push tolerances to their limits, while OEMs still expect faster ramp-ups, tighter reliability targets […]
Temperature monitoring is a fundamental requirement in modern electronic systems, ranging from consumer appliances and industrial equipment to power electronics and laboratory instruments. An LED temperature display circuit using LM3915 and a thermistor offers a simple, reliable, and visually intuitive way to indicate temperature variations without the complexity of microcontrollers or digital displays. This circuit […]
