A phototransistor is a semiconductor device that combines the properties of a photodiode and a transistor. It is sensitive to light and provides amplified electrical output based on the light intensity incident on its base region. Phototransistors play a vital role in optoelectronic applications such as light sensing, encoders, switches, and signal transmission, owing to […]

Difference Between SCR, DIAC and TRIAC
In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]
Piezoelectric Transducer – Construction, Working and Applications
The term “Piezo” in Piezoelectric Transducer originates from the Greek word piezein, meaning “to press” or “to squeeze.” This etymology reflects the fundamental principle of piezoelectricity—a phenomenon in which mechanical pressure generates an electrical voltage. Piezoelectric transducers (sensor / Actuator) harness this effect to convert mechanical energy (such as pressure, force, vibration, or acceleration) into electrical […]
Carbon Composition Resistor Construction, Working & Applications
Let’s Explorer Carbon Composition Resistor symbol, construction, working, types, value reading, advantages, disadvantages, and applications explained in the clearest way. Carbon composition resistors were once the most common type of resistors used in electronic circuits. Though largely replaced by more modern resistor types today, they still hold importance in high-energy pulse and vintage circuit applications. […]
Types of Resistors with Symbol, Classification and Applications
Resistors are fundamental electronic components that limit, regulate, or set the flow of electric current in a circuit. While they may appear simple, there are different types of resistors designed for specific purposes and operating environments. Now you know the basics of resistance and its role in circuits. Let’s dive deeper into the all the […]
Constant Current Diode Symbol, Construction, Working & Applications
Constant Current Diode (CCD) (also known as Current Regulator Diodes, or simply CRDs) are unique semiconductor devices designed to maintain a constant current over a wide range of voltages. They are extremely useful in circuits where a stable and predictable current is crucial, regardless of voltage variations. In this article, we will cover the Symbol, […]
